Now that redsn0w has been updated to jailbreak iOS 4.2.1 you may be wondering what's involved in actually jailbreaking your iPhone. Here are some tips and instructions to help.

SportsLEATHER is just as easy to apply as a film, yet it adds the touch and feel of real leather to your iPhone. No more scratch-prone plastic or breakable glass backs. Supple leather forms to curves and the sportsLEATHER design of your choice is custom-fit to your specific iPhone model.

Just one day after Apple's release of the iOS 4.2 firmware update, iPhone Dev-Team has made public the first updated jailbreaking tool for Mac OS X and Windows. Redsn0w version 0.9.6b4 can be used immediately for those who are not concerned about using the ultrasn0w unlock. iPhone 3G and older iPhone 3GS users will be happy to know that the jailbreak is untethered.

For newer iPhone 3GS and iPhone 4 users, this version currently requires a computer to boot into the jailbroken state. The iPhone Dev-Team is working with @comex on a fix that would untether the iPhone 4 jailbreak once and for all. Unlockers can expect a new version of ultrasn0w for the iPhone 3G and iPhone 3GS as early as next week.
