Hi all, I have an AT&T locked iPhone 4s and I'm trying to unlock it so I can run it on Cincinnati Bell's network; I'm wondering if anyone else has tried this with success. If so, what method did you use? I've seen a lot of videos on YouTube where people were able to unlock their iPhone 4s's using a T-mobile SIM card, but that method doesn't work when I follow the directions and insert the Cincinnati Bell SIM card in place of the T-mobile card. I apologize if this question has been asked or answered in other threads, but I'm desperate and I would be grateful for any help anyone can provide. Thanks in advance!
