Timeline

2010

October

• October 9 -- In order to push Chronic Dev Team to change the exploit used on greenpois0n, Geohot released an unstable BETA version of limera1n. This BETA release is still buggy and uses an unstable version of the userland exploit made by comex to untether the jailbreak process. This version is said to cause problems with some devices and does NOT work on the iPhone 3GS with new bootrom.

• 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 patchable and may be a universal one.

• October 6 -- Chronic Dev Team issues expected ETA of greenpois0n as October 10, featuring the new SHAtter exploit for all A4 processor devices.

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.
