We had reported yesterday that Comex had indicated that he plans to release his Spirit like tool in a few days and doesn’t plan to wait for Apple to release iOS 4.1, which it had seeded to developers of its iPhone Developer Program last week.
iPhone Dev Team have also provided some more interesting details about the progress they're making to release tools to jailbreak and unlock iPhone.
We're gonna be able to give you an unlock with the jailbreak.
He went on to add how users will be able to unlock their iPhone:
It will probably be the usual thing where you jailbreak and then install ultrasn0w from Cydia.
MuscleNerd has also indicated that it might be possible to unlock iPhone permanently based on their latest efforts:
Looks like one version of the iPhone4 unlock fits into just two AT commands… @planetbeing 's loader is awesome
Side benefit to this iPhone4 unlock effort: can do seczone dumper tool for those wanting to bruteforce their unlock code
(bruteforcing your phones unique unlock code is huge computational effort, but to start you need seczone dump)
a successful bruteforce of your unique unlock code would give you your permanent unlock, no ultrasn0w needed
Planetbeing or MuscleNerd haven’t provided any details on when they plan to release the tools so looks like will have to patiently wait for iPhone Dev Team or Comex to release their tools.
Meanwhile, you can also checkout Make It Work’s interview with Jay Freeman (aka Saurik) developer of Cydia, the unofficial App store for jailbreak apps where he demonstrates a jailbroken iPhone 4 with Cydia running on it:
Update (25th July, 2010):
MuscleNerd of the iPhone Dev Team has tweeted that there are still facing some issues with apps like FaceTime that need to be fixed before releasing tools to jailbreak and unlock iPhone:
Not to make it a daily thing, but since somehow people thought it would be today: the new JB+unlock won't be out today
(there are issues with important apps like Facetime that need to be figured out…no sense releasing a half-broken JB)
