They're trash. Only one day with them and I can tell this isn't going to work. I bought the phone from the Apple Store online the T-Mobile variant. How do I switch it to AT&T ? I heard if you buy an iPhone from Apple online on for T-Mobile it's compatible with AT&T. I chatted with ATT and they said I should be able to bring it and they can switch it over, but she sounds like she doesn't know what she's talking about.
