The well-known iPhone hacker George Hotz aka Geohot has finally released the limera1n jailbreak for iPhone 3GS 4.1/4.0/4.0.2/4.0, iPhone 4 4.1/4.0/4.0.2/4.0, iPod touch 3G 4.1/4.0/4.0.2/4.0, iPod touch 4G 4.1/4.0/4.0.2/4.0, and iPad 3.2.2 hardware. Currently limera1n only works on Windows, but it should come to Mac and Linux soon.
Grab the limera1n download for Windows from this link. The limera1n jailbreak software doesn't use the SHAtter exploit unlike the greenpois0n jailbreak which does. When Geohot released limera1n he upset the greenpois0n jailbreak team (Chronic Dev Team) because Chronic Dev Team didn't want 2 different exploits being released at once. Geohot has forced Chronic Dev Team to save the SHAtter exploit and remake greenpois0n to use the same exploit that Geohot used in his limera1n jailbreak. Unfortunately this move by Geohot may delay the greenpois0n jailbreak, and push it past the original release date of 10/10/10 10:10:10 AM GMT.
The jailbreak scene is really getting interesting. I'm sure a lot of you will be happy though because limera1n has support for 3GS and 3G (oops, it doesn't support 3G for that you can use redsn0w), unlike greenpois0n which only had support for 4th gen devices because it used a different exploit. If you are satisfied with limera1n let us know in the comments below.
