Step-by-step Tutorial: How to (Un)Tether Jailbreak and Unlock iPhone 3GS Using RedSn0w 0.9.10 (Windows) [iOS 5.1]
UPDATE: Apple released iOS 5.1.1 and has stopped signing iOS 5.1, so you can NOT restore to 5.1 any more (both original and custom), unless you have saved your SHSH keys for 5.0.1. If you are on 5.1 you can jailbreak with redsn0w. iOS is also tethered jailbreakable with redsn0w.
This is step-by-step instructions on how to perform jailbreak and unlock of your iPhone 3GS on iOS 5.1 firmware using RedSn0w 0.9.10 for Windows.
If you have iPhone 3GS with an old bootrom version 359.3, the jailbreak is untethered. If your device has bootrom version 359.3.2 and higher, jailbreak will be tethered. You can detect your bootrom version using this tutorial.
Tethered jailbreak means that each time you restart your device you will need to connect it to a computer and run redsn0w.

iH8sn0w have found a way to downgrade iPhone 4S and iPad 2 to iOS 5.0.1
iH8sn0w, developer of sn0wbreeze and iFaith, has found a way to downgrade the firmware on A5 devices - iPhone 4S, iPad 2.
Using saved SHSH blobs, iH8sn0w was able to downgrade his A5 iPad 2 from iOS 5.1 to iOS 5.0.1. He says his method will also work with the A5X processor once firmware updates are released for the new iPad. That means that it's possible to restore to any firmware you want on A5 devices, as long as you have the SHSH blobs saved.
This is great news for those with the iPhone 4S and newer iPads. As it stands now, if you have to restore for any reason, you will be forced to upgrade to the latest firmware. This could leave you without the ability to jailbreak for some time.

iPad 3 Uses Retina Graphics From iPhone Apps
When the original iPad was released, there weren’t many apps available for the device. So Apple allowed apps developed for the iPhone’s smaller display to run on the iPad by using emulation. The apps could use only a fraction of the iPad’s display. Alternatively, iPhone-specific apps could be run in a 2x mode, utilizing pixel doubling technique to fill the iPad’s display. However, in 2x mode text and artwork look pixilated and blocky.
