Unlock iPhone 3GS On 4.3.4
Hi, I recently got an iPhone 3GS. It is loaded with OS 4.3.4 and has baseband 05.16.02. I looked at the guide here and that combination wasn't listed and I can't seem to find any info on it through google either. Is it possible to jailbreak and unlock this combination? I have seen some for the baseband using an iPad baseband, but those are for iPhones on a different OS. I was wondering if I need to downgrade or upgrade and if that would change my baseband. I'm a little lost, any help is much appreciated.

As far as I know you're stuck for the moment... 4.3.4 is not jailbreakable so you'll probably need to move to iOS 5 for a jailbreak. Unlocking, however, is the real issue. Right now Ultrasn0w supports basebands up to 05.16.00, so even if you go to iOS 5, you'll still be locked.
iPhone 4 users report successful unlocks using a Gevey SIM. No word, however, if it works on a 3GS. This might be worth looking into, nevertheless.

U can't upgrade or downgrade to a specific OS without the shsh ... If you go too a OS that is jail breakable then u can update to iPad baseband but loose gps and it can not be undone or restored in iTunes.
iOS 5 and 4.3.4 is a teathered JB but I don't think u can update to the iPad baseband while running those versions

the latest version of redsn0w does the iPad baseband so go here I've put links where you can find it. http://forums.tipb.com/jailbreak-unl...ml#post1805242 I would suggest going to 5.0 if you can and they haven't stopped signing it yet. This way you will be able to get the untethered JB when it's out. If they have stopped signing however you can go to 5.0.1 with the iPad baseband and you should be able to unlock. Just make sure you know the caveats about the iPad baseband so you don't screw up your phone trying to upgrade later or something.
