folks, my girlfriends brother bought an iphone from ebay adverted as having a cracked screen but working 100% so I replaced the screen for him and now from what I can see I think the IMEI number has been blocked (phone been clocked as lost or stolen). anyone have any ideas? I know that on the phone software 1.1.4 you could change the IMEI number (Yes I know its illegal...) but you cannot with the 3.1.2 the latest iphone software. Does anyone work in O2 (or any mobile network carrier) that can check if the phones blacklisted the IMEI number is 011774006461336. again any other ideas would be great i've tried using all the programs like ultrasnow to unlock it etc but im still stuck... advise if possible cheers folks
