Use your iPhone in landscape mode turning it into a mini-iPad
You can use your iPhone in landscape mode thanks to a third party tool that is available on the Cydia store. The app is called SBRotator, costs $1.99 and requires a jailbreak to install. Once activated, it will adjust the iOS icons to fit into the horizontal iPad-style layout by adding an additional row of icons, or you can set it to scale the icons to size automatically. You can also have it hide the icon names like in the image above.
What I think is most interesting about SBRotator is just how much it makes the iPhone (or iPod touch) look and behave like a miniature iPad. Once the iPhone has been placed into landscape mode, it really starts to look more like a tiny tablet than a phone.
Like I said, the app requires a jailbreak to work because it’s installed through Cydia. You can download redsn0w 0.9.6b6 if you need it, but be aware that newer iOS devices require a tethered jailbreak at this point.
Jailbreak or not, this is definitely a cool app. Thanks to MacStories for finding it a few days ago (screenshot is from there too).
