    My friend wants to upgrade his iphone 3g 8gb from 3.0 to 3.1.2. His iphone is currently jailbroken and unlocked. Is it possible to upgrade to 3.1.2 without losing the unlock? How can I upgrade?

    Once he upgrades the firmware, the device will need to be unlocked again. As long as you use the 3.1.2 firmware to upgrade, you will have no problems unlocking. It is best to use a Pwned firmware if you have the 4.26 baseband. That way, you can use Ultrasn0w to unlock it, which doesn't have the reported problems that blacksn0w is said to have. Otherwise, once updated to 3.1.2, if you're running the 5.11 baseband, just use Blacksn0w.

    to upgrade, you must have the iPhone 3.1.2 firmware file, and hold SHIFT and click on RESTORE in iTunes. That will let you browse for the 3.1.2 firmware file.
