My ATT iPhone 4 received unlock OK yesterday so I hooked it up to iTunes w/ ATT SIM installed and did the restore. Unlike when I unlocked my ATT 3GS w/ Vodaphone SIM installed, neither iTunes nor the iPhone reported my phone was unlocked. So just wondering if the "your iPhone is unlocked" verification line only appears when a SIM not belonging to the original carrier is installed. Or should the "unlock" notice appear with the ATT SIM too? I'd test it w/ another microSIM but I don't have another and don't want to cut my Vodaphone.
