    So I've found a place to grab a custom built 3.1 FW for the Iphone 3G. I'm currently on 3.01 JB already.

    My questions is there are 2 types of custom 3.1 firmware, one being for AT&T customers, one being for Non-AT&T customers. I am currently contracted with AT&T but thinking I wouldn't mind being able to use the Unlock and not be Restricted to AT&T only.

    So is it safe to use iTune to restore to Non-At&T customer 3.1 firmware? or does that breaks the baseband and I can't MMS? My thing is I also have a T-Mobile company acct sim therefore once my minutes are used up with AT&T, just swap the sim card to T-mobile and continue using my beloved 3GS.

    I'd try the non AT&T one first, it unlocks the carrier so it shouldn't remove your abbility to use AT&T.
