My understanding is that you CAN update an officially unlocked phone via iTunes and it will stay unlocked.

To jailbreak, use QuickPwn.

If everything goes horribly wrong, you can always restore in iTunes.

If it is a truely unlocked iphone, you can restore it and jailbreak it all you want and it is still unlocked forever. But if any of your friend's "officially unlocked iphones" got relocked it's cause they were never officially unlocked in the first place. So you have nothing to worry about.

I did jailbreak my cousin's iphone 3g which he brought and use in Hong Kong, he visit here in Hawaii and using tmobile service with the original sim card from HK, I jailbreak it with quickpwn 2.2 and it is still working fine with tmobile.

I have a vodafone NZ unlocked 3G that shipped with 2.0. I have updated through every version to 2.2.1 and JB'd on a few firmwares (including currently on 2.2.1). I have never had an issue with sim's or activation etc.
