Ultrasn0w has been updated to version 1.2.3 with support for preserved baseband running iOS 4.3.3. In other words, ultrasn0w 1.2.3 does not unlock new baseband, but it does work to keep your unlock if you have been tugging along iPhone 4 with 1.59.00 or iPhone 3G & 3GS with 4.26.08, 5.11.07, 5.12.01, 5.13.04, and 6.15.00.

If this applies to you, you’ll want to use PwnageTool 4.3.3 (Mac) or Sn0wbreeze (Windows) to jailbreak while preserving your old baseband and updating to iOS 4.3.3.

Install Ultrasn0w Unlock for 4.3.3

After you are jailbroken, ultrasn0w is installed through Cydia. You can generally do this just by searching for “ultrasn0w” but if that fails:

• Add http://repo666.ultrasn0w.com as a source repository to Cydia
• Search for “Ultrasn0w 1.2.3” and install
• Reboot your iPhone

Assuming you have supported baseband and everything is done correctly, the iPhone will boot unlocked and ready for another SIM card. Remember that many unofficial carriers do not support 3G networks so you should disable that in network settings if things aren’t working as expected.

Jailbreaking iOS 4.3.3 is made easy with the redsn0w utility, if you’re not sure what to do then this guide will walk you through the process. The tutorial is geared towards the iPhone, but the steps would be the same for an iPod touch and iPad. This is an untethered jailbreak, meaning you can reboot freely without concern.

Requirements before starting:

• Compatible hardware includes: iPhone 3GS, iPhone 4 GSM, iPad 1, iPod touch 3rd & 4th Gen
• You need the latest version of iTunes (10.2.2)
• Update your iPhone, iPad, iPod touch to iOS 4.3.3 before proceeding
• Download Redsn0w 0.9.6rc15 (Mac & Windows versions available)
• Download iOS 4.3.3 IPSW for your specific device
• About 10 minutes of your time

If you’re familiar with redsn0w and jailbreaking in general, this new version is not much different, although you do now have the ability to enable multitouch gestures during the installation. All ready? Let’s get started…

PwnageTool 4.3.3 has been updated and released to provide an untethered jailbreak for iOS 4.3.3. The update supports jailbreaking iPhone 4, iPhone 3GS, iPad 1, iPod touch 3rd & 4th gen, and Apple TV2. Support is absent are iPad 2 and iPhone 4 CDMA.

Download PwnageTool 4.3.3

PwnageTool is for Mac only. Windows users will need to use sn0wbreeze or redsn0w.

The PwnageTool update comes alongside redsn0w 0.9.6rc15, but PwnageTool differs from redsn0w in that it allows Mac users to create customized versions of their IPSW. This is a necessary procedure for iPhone users who wish to preserve baseband and some carrier unlocks. If you are just looking to jailbreak your device, redsn0w is easier, but does not offer the ability to preserve baseband with custom IPSW.

Redsn0w 0.9.6rc15 has been released to jailbreak iOS 4.3.3 untethered on any of the following compatible hardware: iPhone 3GS, iPhone 4 GSM, iPod touch 3rd Gen, iPod touch 4th Gen, iPad (original, not iPad 2), and Apple TV2. For those wondering, iPad 2 is still not jailbreakable.

As usual, you’ll need to download iOS 4.3.3 IPSW for your corresponding device before getting started. The iOS 4.3.3 updated focused on alleviating the tracking cache bug, and otherwise offers no feature enhancements.

Download Redsn0w 0.9.6rc15

Update: Redsn0w 0.9.6rc16 has been released, the download links have been updated to reflect this.

Mac & Windows versions are available, these are direct download links:

• Download now (Mac)
• Download Now (Windows)

If you aren’t sure what to do, follow our guide to jailbreak iOS 4.3.3 using redsn0w.

The Dev Team notes that if Windows users are having problems running redsn0w, that they should set CPU affinity to 1. Additionally, running Redsn0w in XP Compatibility mode can help alleviate some errors. Mac users don’t have to worry about any of this.

Alongside the new version of redsn0w are updated versions of PwnageTool for creating customized IPSW, and a new version of the ultrasn0w unlock. Be aware that the ultrasn0w update relies on the preservation of old baseband and is not considered a new unlock.

If you like to keep an eye on system resources and you want to branch out from the GUI Activity Monitor, check out htop for Mac. htop is basically a significantly improved version of top, which lets you monitor system resources, CPU core load, memory use, load averages, and view and manage individual running processes.

If you’re coming to Mac from the linux world, you’re probably already familiar with htop, but if you’re not here’s why it’s better than top: for starters, it just looks better and is easier to read thanks to an improved layout and use of ANSII colors, but beyond that it’s great because it functions much like a task manager, allowing you select and then renice or kill processes as needed. I find this easier than manually entering PID’s through top. Anyway, let’s get htop installed in Mac OS X via a package manager like Homebrew or MacPorts.

Do you have some source code, text, or a command string that you want to securely transfer from one Mac to another? Combining the command line clipboard tools pbcopy and pbpaste with SSH we can do exactly that, and it doesn’t matter where the other Mac is located: be it LAN, WAN, or anywhere.

Here is the basic command syntax:

pbpaste | ssh username@ipaddress pbcopy

For transferring data on a LAN, you can use another Macs hostname or IP address.

This is highly useful because using this method is secure, plus it will not mangle special characters or code in the manner that many email and IM clients will.

iOS 5 may include the ability to push over-the-air updates and patches to iOS, meaning you’d be able to update your iPhone or iPad without hooking it to a computer with iTunes. More specifically, iOS 5 is reported to include the feature, but it will be future versions of iOS 5 take advantage of the OTA updating, perhaps as iOS 5.1, according to a report by 9to5mac.

iOS Over-The-Air is a Step to True “Post-PC” World
Over-the-Air, or OTA, would be an important step to turning the iPhone and iPad into true “post-PC” devices, since it would free the hardware from the tethered world of desktop updates. The next question this poses regards iOS backups that are typically synced with iTunes, but that could theoretically be handled by a cloud based wireless syncing solution which is rumored to appear sometime in the future.

OTA Updates & Bandwidth Limits on Data Plans
The major problem with Over The Air updating is the increasingly strict world of wireless bandwidth limits imposed by carriers. When you consider that most software updates weigh in at hefty sizes (iOS 4.3.3 is 670mb, for example), you have to wonder how OTA iOS updates would work. There are several ways to address this, here are three possibile solutions:

1. Allow OTA updates to only download over WiFi, in a similar fashion to how FaceTime only works on WiFi connections
2. Split the updates into smaller incremental patches, but allow them over either cellular or wireless, as 9to5mac theorizes
3. Apple reaches a deal with wireless carriers to allow OTA iOS updates to be ‘whitelisted’ from the bandwidth allowance of a users data plan, allowing users to get updates without counting against their allotted monthly limits

The report comes from 9to5mac, who cites “multiple sources” who say that Apple is working specifically with Verizon on the matter. Although they say there is no information on OTA support with other carriers, it would be unlikely for Apple to not pursue a widespread adoption of the feature across all carriers.

iOS 5 is expected to make an appearance at WWDC 2011, which begins June 6.

The upcoming release of Mac OS X 10.7 Lion will be distributed primarily as a download through the Mac App Store. This information comes from AppleInsider, who says the following:

The Mac App Store… will become the de facto method for obtaining the Lion upgrade, people familiar with the matter have revealed. Users will be able to upgrade instantly without the need for physical media by purchasing Lion through the Mac App Store.

Distribution of Lion through the Mac App Store for all users is not too surprising considering it’s the primary method for developers to download and install the Developer Preview releases. This is not to say that a corresponding DVD installer will not be released alongside the digital distribution. Last month, a placeholder for a Lion installation DVD showed up on German Amazon, and there continues to be a possibility that Lion will also appear on USB installer keys for MacBook Air and Mac Mini Server users.

Mac OS X Lion is expected to make a significant appearance at WWDC 2011 in early June.

iOS 4.3.3 has been released, the update is primarily aimed to address the storage of iPhone tracking cache and database files that caused a media conniption and some amusing comics earlier in the month.

You can download iOS 4.3.3 directly from iTunes and that is recommended for most users. Otherwise, you can use the direct links below:

iOS 4.3.3 Direct Download Links

These are direct download links for iOS 4.3.3 IPSW files from Apple’s Servers. Right-click and “Save As” the file, it should be a .ipsw extension and NOT a .zip:

• iPhone 3GS
• iPhone 4 GSM
• iPhone 4 CDMA – iOS 4.2.8
• iPad 1
• iPad 2 – WiFi model
• iPad 2,2 – AT&T GSM
• iPad 2,3 – CDMA Verizon
• iPod Touch 3rd Gen
• iPod Touch 4th Gen

If you just update iOS through iTunes, these IPSW files are not any use to you. Nonetheless, if you want to learn to use IPSW files to update iOS manually you can.

The brand new updated iMacs for 2011 include a seemingly out of place setting in the Keyboard System Preferences: Keyboard Illumination. That’s right, despite being a desktop machine that ships with the same familiar keyboards we all currently know, the new iMac includes the same keyboard illumination option that MacBook Pro’s do. Does this suggest Apple is working on an external backlit keyboard, and if so, was it originally intended to ship with the new iMacs?

This is a neat Mac trick I accidentally discovered: not only can you launch apps from the toolbar of a Finder window after placing them there, but you can drag folders into any Mac OS X Finder window toolbar as well, and it will stick there allowing for easy access.

The do this yourself, you just need to drag a folder into the toolbar of any Finder window. Any folder works, but there are some cool unexpected extra styling that comes with some folders that we’ll get to in a moment. The change then carries over to all other active Finder windows, with the folder icon appearing there.

Apple has released a new iPad 2 commercial titled “If You Asked” and it follows well in the footsteps of the “We Believe” TV ad that first launched with the device. The audio of the commercial says:

If you ask a parent, they might call it intuitive… if you ask a musician, they might call it inspiring… to a doctor, it’s groundbreaking… to a CEO, it’s powerful… to a teacher, it’s the future… if you ask a child, she might call it magic… and if you asked us, we’d say it’s just getting started…”

Now, if you asked me, I’d say the iPad 2 is still nearly impossible to find in stock at a store, so buy it online and wait a week or two instead for delivery.

Anyway, I like these new commercials, they feel a bit more sentimental than some of the past Apple ads and I think that’s a good thing. Apparently it started airing tonight, so keep an eye out for it if you’re watching TV.

Want to help test Chrome development releases and be on the absolute cutting edge of web browser development? Try out the newly released Google Chrome Canary for Mac OS X, which Google says is aimed at the “bravest” of Chrome users.

Chrome Canary installs as a separate app to the stable Chrome builds, so you don’t need to worry about overwriting your existing app or Chrome resources. Canary is then automatically updated to the latest build and offers no testing before each release, meaning you’ll have lots of interesting features and improvements alongside a slew of bugs and crashes, Google even says “we expect it to be unstable and, at times, unusable…” so be prepared to fill out crash reports.

If this sounds like fun to you, you can download Chrome Canary from Google.com and help out.

I like Chrome a lot but I’m partial to stable browser releases, nonetheless Canary is fun to play around with to see what’s cooking over at Google. Heads up to MacGasm for the tip.

If you have recently upgraded your Mac RAM, or if you are experiencing strange system crashes, it’s a good idea to test your memory modules integrity using a free tool called memtest.

Essentially, memtest is a utility designed to stress test RAM for errors. Without getting overly technical in the explanation, memtest works by writing random data to the RAM, then verifying that the data written to the RAM is readable and without conflict. If errors are detected using this method, it typically means there is a faulty memory module, and that’s why memtest is such a valuable tool. Though it’s technical in nature, it’s quite easy to use, so let’s begin.

Uninstalling apps from Mac OS X is set to get even easier in Lion, thanks to usability cues taken from iOS. Using Launchpad, you’ll be able to just click and hold on an icon to cause the familiar icon jiggle and “X” to appear, click the X and the app will delete.

One quirk though, as MacRumors notes, is that this only works on apps installed through the Mac App Store. Other third party apps currently can’t be deleted through LaunchPad, which creates a strange user experience inconsistency, but this may change by the time Lion is released to the public this summer.

Update: Some users are reporting that they can delete any third party apps, not just those from the Mac App Store, through LaunchPad in build 11a444d of Lion Developer Preview. Here’s a screenshot of this:

This screen shot came from a thread on MacRumors forums, although it’s not clear why many users on the same Lion build do not have this ability.

Update 2: It looks like any apps installed after updating to build 11a444d can be deleted through LaunchPad, but apps installed before the recent update can not be deleted. Probably just a bug.
