This allows 3G/3GS users that had upgraded to the iPad baseband, thus losing the GPS function and the ability to restore to stock firmware, to get back to an iPhone baseband, making their devices behave as intended again, as well as being unlockable by ultrasn0w.
• June 14 -- iPhone Dev Team releases a developer version of redsn0w (0.9.13dev1), which jailbreaks limera1n susceptible devices running iOS 6 beta 1.

• November 22 -- Apple releases iOS 4.2.1 (respectively 4.2 for Apple TV 2G)

• October 12 -- Chronic Dev Team releases greenpois0n after switching its exploit from SHAtter to limera1n, in the hope that SHAtter remains for 5th generation devices. (The exploit limera1n uses was fixed in the iBoot revision found in iOS 4.2 beta 2, which means Apple knows about the vulnerability and the next bootrom revision may have it patched.)
• October 10 -- Following the first limera1n beta release, geohot released multiple versions, each fixing bugs affecting previous releases. Chronic Dev Team officialy anounces that, in order to keep SHAtter undisclosed and possibly preserve it for 5th generation devices, greenpois0n would be delayed in order to incorporate this new exploit limera1n uses.
• October 9 -- In order to push Chronic Dev Team to change the exploit used on greenpois0n, geohot rushed out a beta version of limera1n.
• October 8 -- Geohot comes back to the scene with a new bootrom exploit believed to work on all devices, as shown on the resurrected limera1n web site. He prompts Chronic Dev Team to use his exploit instead of SHAtter, but, since greenpois0n is already scheduled to October 10, it may be not possible. Geohot ETA'd his limera1n release to October 11, if greenpois0n can't be changed to use this new exploit. This decision, however, would burn 2 bootrom exploits: SHAtter itself and the one used by limera1n, which is unpatchable by firmware updates.
• October 6 -- Chronic Dev Team issues expected ETA of greenpois0n as October 10, featuring the new SHAtter exploit for devices with the S5L8930.

Jailbreaking and installing this patch is currently the only way for users of first generation iPod touches and iPhones to protect themselves against malicious use of the exploit.
• August 11 -- Apple releases iOS 4.0.2 for iPhone/iPod touch and iOS 3.2.2 for iPad as a hotfix for Star's exploits. Ultrasn0w's exploit remains, since there's no baseband update on those versions.
