Upgrade/Unlock iPhone 4 - Help
I've had my iPhone 4 for about 6 - 8 months.
Its jailbroken on firmware 4.0.1 with ultrasnow installed (Baseband of 1.59.00)
I've been avoiding updating my firmware in fear of losing my Unlock which would ultimatly make my phone useless.
I would like some information on Updating my firmware to 4.3.1 and having an Unlock still work, hopefully keep my baseband of (1.59.00)
I know there are a few tutorials/guides online, but would still like to be reassured these methods work.
If anyone has any information for me, it would be greatly appreciated.
