I cant believe what has just happened! I am now factory locked on another carrier! My girlfriends 3G has been locked to O2 from out of the box since new but JB and unlocked by Dev team software, was on 3.0. I updated to 3.1.2 via iTunes. When the phone switched back on it activated in iTunes and downloaded a carrier update, as Orange UK are about to start selling iPhones from next week I believe my girlfriends iPhone is now factory locked to Orange UK as I got full reception and havent even ran BlackRa1n or sn0w as of yet! Just tried an O2 sim and now states invalid sim inserted! Now Im only going to jailbreak and not apply the unlock. My theory is Apple are going to ship O2 devices and simply change the lock status within iTunes on first activation! Anyway I can prove this? I will try my 3GS as i'm on 3.1 JB and soft unlocked also on Orange UK pay monthly. Can anyone else try this? UPDATE! Just did the same on my 3GS and it is now factory locked to Orange rather than O2! I restored the 3G to 3.2.1 as I had Blackra1n downloaded and ready to use. After the iTunes restore the phone displays "Connect to iTunes" I connect it and it then says "Activated" and Orange UK was showing, this is without using Blackra1n. This happened on both phones. I've only JB'ed not unlocked and both are fully working on 3.2.1 officially on Orange UK with full servies. My options have gone for editing the "Cellular data settings". Both phones are fully working without having applied a software unlock. Means apple are selling the phones locked and activate depending on what sim card you use. Please try this and let me know!
