Last night I was made aware that iPhone 3GS owners with baseband on iPad could have problems with an iOS 4.3.4 update. Since I don’t have an iPhone 3GS with baseband on iPad I could not test the problem but I have researched, and I discovered that many users have met this problem so far and assume that some of you are in the same situation.
Apparently after the iOS 4.3.4 update, some iPhone 3GS owners with baseband on iPad cannot make jailbreak and cannot use the terminal neither using the Tethered Mode function. redsn0w 0.9.8 beta 3 would not work at all, the terminal would remain in Recovery Mode and the only solution would be to downgrade at the iOS 4.3.3.
Unfortunately, the downgrading is not as simple as normal after displaying the error in iTunes, the terminal goes automatically in DFU mode, for some. If the device enters in DFU mode then it cannot be removed from this state using TinyUmbrella because the program was not designed for it.
If the device has entered in DFU mode you have 2 options: either use redsn0w for untethered jailbreak on iOS 4.3.3, either keep the lock + home buttons until the apple appears on the screen and the device will enter in the Recovery Mode where you can get it with TinyUmbrella. My advice is to use directly redsn0w for jailbreak because you will still need ultrasn0w to unlock, anyway you have to do jailbreak.
The problem seems difficult but it is simple, easy to fix.
