    Hey guys,

    Just got my at Iphone 3Gs It has firmware 3.0.1 and baseband 04.26.08. It was already unlocked using Ultrasn0w (Cydia). First, should I upgrade to 3.1.2 or just leave it alone? If I do the upgrade to 3.1.2, how do I keep the 04.26.08 baseband? I've read a lot but still a bit confused. Thanks.

    use pwnage tool to build a custom ipsw. that will only update your fw.
