I had my 4S remotely unlocked through a ebay seller because after I updated to ios 6 my phone didn't work. After having the unlock performed the phone worked. 3 days later I powered down my phone and when I restarted it I had no signal (Searching..../No Service) I did a restore twice and its still not working ffor me. Right now its in the "Set up iPhone" screen. Should I select "set up as new phone" or "restore from iTunes Backup". Any suggestions? Also if this works does it mean that everytime I power down I'll have to go through these steps. The sim card that I have is not the one from the original carrier. Any help would be greatly appreciated
