iphone 3GS Jailbreak/Unlock Question

post #1 of 5
Thread Starter 
I accidentally updated it to 4.3.5 without knowing about the base band problem.

So..it's at Modem Firmware 05.16.02 or something.

I'm assuming there's no jailbreak/unlock for 4.3.5 and I'll have to wait for ios5 or something to be released? If so, any idea when that's gonna' happen?

Yes and no.

Assuming you had the phone previously jailbroken, you can downgrade to any firmware you have blobs for. As long as you jailbroke [jailbreak-ed? idk grammar fails me right now] your phone will have the blobs automatically backed up on Sauriks server, TinyUmbrella can get them for you, so don't worry. Here's a simplistic guide what can get you downgraded without any real issue

An unlock will only be possible if you have a 3GS with an Old Bootrom, here's a quick and dirty guide to test / check it.

If you do have an old bootrom, you can upgrade your baseband to the iPad 6.15.00, the latest version of redsn0w can facilitate this, though you will need the iPad IPSW for 3.2.2 iirc. Then just follow the steps within redsn0w to kick your baseband up to 6.15.00.

Here's the problem with the iPad baseband. You 90% of the time have no GPS feature at all, you can never really downgrade your baseband and can't hide it, so your warranty is busted, you're forced to use custom firmware cookers like sn0wbreeze [windows] and pwnagetool [mac], otherwise your restores will fail with official IPSW's.

So that's part one.

If you have a newer bootrom, then you can still downgrade to something like 4.3.3, but you will not retain an unlock since your baseband is permanently upgraded to 5.16.02. Though you can set up a jailbreak after you've downgraded.

As for iOS5 release date... it's highly speculated that it will be before October 4th, which atm is the date it seems Apple will release information / have a whole press event on the iPhone 5. So waiting until then might be an option, but iOS5 is still in beta to date.

I think that covers everything..

Jailbreak, most likely.

Unlock, if I had to guess... maybe December at best. Unlocks always come waaaaaaay after iOS releases... not even to mention th last unlock was for 4.2.1 iirc, and I'm sue you know how many newer iOS versions have been released since then without an unlock :\\

Hi, No problem. Nothing to worry. you can unlock your updated iPhone 3GS safer and easier using remote unlocking service. You can get the remote unlocking service for an iPhone 3GS from www.Simpleunlocking.com at affordable cost with easy unlocking guide. This is a permanent unlocking method and doesn't require a jailbreak too. Good luck.
