GeoHot Hints Working Exploit To Unlock Baseband 05.12.01

With the release of iPhone OS 3.1.3, Apple pushed the baseband to version 05.12.01 which remained unlockable and hence created woes for lots of jailbreakers who had accidentally upgraded to the latest firmware. Then, a few days back, @sherif_hashim tweeted he had crashed baseband 05.12.01, which he handed over to the iPhone dev-team. However, no ETA was announced as to when the new unlock would be released, since it would serve better to have it out in the open with the release of the next-gen iPhone OS 4.0, or perhaps OS 3.2.

Update: The unlock for all basebands, including baseband 05.12.01 is out. Check it out here.

Yesterday, GeoHot revealed he too had a working exploit for the new baseband. His tweet, as shown below, did not make much sense before @visnet_ tipped iHackintosh providing some insight by revealing excerpt of an IRC chat between himself, @geohot, @Par4doX, @Evan, @MuscleNerd, @He (check out screenshots below). Hotz had two working exploits for baseband 05.11.07 but chose to use xemn in his BlackSn0w unlock since it was already public. The other exploit remained open, and apparently through Hotz’ testing, it remains unpatched in the new 05.12.01 baseband.



With this latest development, seems like the dev-team and geohot both have working exploits for baseband 05.12.01. What remains to be seen is whether they are both unique ones, or have both the iPhone master-hackers caught the same fish. There still is not ETA for any unlock release from either the parties, but geohot may take the first shot since he’s partying this weekend.

    well if geohotz can earn from us more than how much apple paid him not to release his work, then maybe we can use his jailbreak and unlock!

  4. I have iphone 3G with bootloader 05.09, ICE2-05.12.01 on os 3.1.3. I have searched the web for a solution for weeks and can’t find one. Is there a thread I can subscribe to that will have an answer to this?

  6. OMG !!! just counting the days to hopefully unlock my iphone 3g bb 05.12.01 bootloader 05.09… i`m just sooo tired to use it like a nice and expensive ipod touch with camera…

  7. To be honest, I am myself eagerly waiting for that unlock. But in all likelihood, that may not happen until Apple’s next OS release, that is 4.0. So I guess we still have to wait πŸ™‚
