I sold my iPhone on ebay today and am trying to unlock it. I chose iLiberty+ because I have a PC. I restored the phone, ran iLiberty+, choosing Jailbreak, Activate, YouTube Fix, Unlock, and Downgrade to 3.9FakeBlank. I also told it to install the Installer. Everything worked like a charm until I tried to test YouTube. Could that be because I have an AT&T sim card in my phone? I read somewhere on these boards that if the phone was not activated through iTunes and has an AT&T sim, that YouTube won't work. Is that the case? If so, how can I test this before I mail this phone to my buyer? I'm not sure if I can find anyone with T-mobile around here. Besides the YouTube Fix from iLiberty+, I tried the Youtube activation through installer. That didn't help either. Also, after I unlocked, iTunes came up and synced with the phone (although I had nothing set to sync, so music or contacts, etc. was moved to the phone). Was it supposed to do that or will that cause a problem? Thanks for any help!
