iPhone SIM-locked again after software restore!
Despite everything i was thinking - and writing in this forum - the unthinkable happened today: When i tried to upgrade my unlocked iPhone from 1.0.0 to 1.0.2, something went wrong. After starting the upgrade, iTunes showed an error message claiming that the upgrade failed with error -1. iTunes left me the only choice to restore the phone, what i did. After the restore, the phone was SIM-locked again. I'm not sure what was causing the re-locking of the phone - but if you want to upgrade your phone to a new software version - BE EXTREMELY CAREFUL!
