What kind of iPhone? Original, 3G, 3GS? If it's unlocked and jailbroken... updating it will remove the unlock and jailbreak, there's tutorials out there to unlock and jailbreak. I think it's called yell0wsnow / ultrasnow, I'm not really in the loop. My iphone is still on 2.x and I just used QuickPWN with firmware file and 2 baseband's, it was real simple.

Depends how the phone was unlocked. If it's factory or carrier unlocked then performing updates will not change this. As mine is carrier unlocked and I have no problems updating whenever there is one.
