If your iPhone or iPod has been acting strangely or not working, it’s worth checking the “Liquid Contact Indicator” locations as shown in the image above from Apple, this may give you a hint of what’s wrong with your hardware.

If the sensors shown in the pictures are red, you may have water damage. I say may because the sensors can be tripped occasionally by high humidity or even just a small rain drop, so it’s possible the sensor is red but you don’t have any damage. On the other hand, if you definitely dropped iPhone into water or it sustained substantial liquid contact that you’re aware of, you’re going to really need to take some immediate action to try and preserve the phone, drying it out for as long as possible so that none of the internal components have retained moisture.

Apple is planning to eliminate traditional retail box software in their stores in favor of digital distribution through the Mac App Store, according to a report from MacRumors. Apparently they heard the rumor from someone, and then cite Apple’s new “Personal Setup for Mac” walkthrough service as further evidence of the move.

Installing software through the Mac App Store is certainly more convenient than using a physical installation DVD, but there are some issues with this method. As MacGasm points out, several major software companies have yet to board the Mac App Store train, some may never jump ship, most notably Adobe and Microsoft with their high priced productivity suites. The solution to this might be in the form of USB based software installers, like the reinstallation drive that comes with the 2010 MacBook Air, which would be a welcome change.

Perhaps we’ll see this change in place by the launch of Mac OS X 10.7 Lion?

The first Verizon iPhone 4 jailbreak has been made available to download as an update to GreenPois0n RC5. The update comes as RC5.4 with the major change being support for jailbreaking the Verizon iPhone 4 running iOS 4.2.6.

Currently RC5.4 is available for Mac and Windows users:

• Download Now (Mirror 2) (Mac)
• Download Now (Mirror 2) (Windows)

As pod2g notes, GreenPois0n RC5.4 should be considered as ‘early adopter’ software, so there may be some bugs to work out still. Our guide on how to jailbreak with GreenPois0n RC5 works the same for RC5.4 and will jailbreak any iPhone, iPod touch, iPad, and AppleTV2.

You can follow our GreenPois0n updates as they become available.

Angry Birds for Mac is a ton of fun, but you probably already know that. Here are some keyboard shortcuts for the Mac OS X version of the game:

Keyboard Shortcuts for Angry Birds on Mac OS X

Some of these you can use anytime and others must require you to be in a current game:

• Command+F – Windowed mode, or toggle between full screen and windowed mode
• Scrollwheel / Two-fingered swipe – Zoom in with a swipe forward and zoom out with a swipe back, same affect with a scroll wheel
• R – Restart the current level and zoom into the target pigs structures
• S – Mute and unmute the game sounds
• P – Pause
• Escape – Toggle the sidebar menu
• Type “open” on levels with a locked treasure chest to open them

These are what I have for now but I’ll update the list if more are available. Apparently there is a cheat mode involved with the “C” key, but I wasn’t able to get it working myself.

If you haven’t played Angry Birds yet you are missing out on some highly addictive gameplay. You can get it from the Mac App Store (Direct Link) or from the iTunes App Store for iOS hardware.

Thanks to Josef for sending in the shortcut list!

If you purchase an app from the iTunes App Store, as long as you use the same iTunes account again, all subsequent downloads of that app are free. This means that if you bought an iOS app for an iPod touch, but you just got a new iPhone, iPad, or Mac you do not need to buy the same app again.

Did you know that your Mac has a built-in FTP & FTPS client? You don’t need to download any additional software or apps to connect to FTP sites from Mac OS X, instead you can connect to remote servers directly from your desktop by using an excellent and little known feature. If you’ve never used the Mac FTP tools before, you will find them incredibly simple and quite familiar, because the connection utilities and server browsing are much like navigating through the normal Mac desktop. Let’s get started.

If you’re trying to remember an exact command you executed via the Terminal but can’t quite come up with it, you can query your command line history to discover old commands that have been run or executed in the past.

This trick to find and retrieve prior commands executed in the command line works on Mac OS, Mac OS X, as well as linux and other unix operating systems too. Anything with a standard history command can use this trick to retrieve prior commands, making it an invaluable tool for systems administrators and command line users.

Need to silence an iPhone phone call and hush the ringing quickly? If you’re getting an incoming call and you want to quickly silence the iPhone, just hit either of the volume buttons to instantly silence the ringer.

Pressing a volume button during an incoming phone call will immediately mute the iPhone and stop the ringer from sounding any alert or vibration, but it does not send the call to voicemail so the caller won’t have any idea that you aren’t listening to the phone ring.

If you like older Apple equipment, you’ll love this picture sent in via Flickr. From Apple II’s to Bondi Blue iMacs, this collection of retro Mac hardware definitely has some bragging rights.

If you don’t have the hardware, you can still get a blast from the past by doing things like running Mac OS System 7 under Mac OS X or even running Newton OS on an iPad.

AT&T has released a new iPhone commercial that jabs at the Verizon network. The commercial features a guy making last minute dinner reservations on his iPhone while chatting on the phone to his partner. The point of the commercial is to brag about AT&T’s ability to use voice and data concurrently, ending with “only AT&T’s network lets your iPhone talk and surf at the same time.”

It’s kind of funny watching the two major US iPhone carriers fight it out over commercials, and Apple is happily caught in the middle here since the product being sold is always the iPhone, the competition is between service.

Recently, Verizon’s “I can hear you now” iPhone commercial started airing, which pokes fun at AT&T’s voice and reception quality.

GreenPois0n RC5 2 has been released, the update to 1.0 RC5 aims to fix an initialization error that some users reported. The “initialized” error seemed to be somewhat random, but it prevented the GreenPois0n jailbreak from continuing on the effected devices.

GreenPois0n RC5 is available for Mac and Windows:

• Download Now (Mac)
• Download Now (Mirror 2) (Windows)

GreenPois0n RC5 works to jailbreak iPhone, iPod touch, iPad, and Apple TV 2.

If you click and hold on any open applications Dock icon, you will launch Expose for just that app and it’s corresponding windows.

You can also access this app-specific Expose with the F10 key (Function+F10 on newer Mac models and keyboards), I’ve used this trick for a long time to quickly switch between windows in a given app and once you get in the habit of doing so it’s hard to go back.

Expose is a great feature of Mac OS X, although I tend to use the Command+Tab application switcher for switching between apps.

There’s a new commercial for the Verizon iPhone that jabs indirectly at AT&T: “It’s beautiful, it’s intelligent, even genius. But does your network, work?” that question is of course answered by the ubiquitous Verizon Guy; “Yes, I can hear you now.”

The takeaway from all this Verizon vs AT&T stuff is this: you can make clearer phone calls with Verizon, but AT&T’s 3G speed is faster.
