    I used the unlock feature in ZiPhone, but I want to be able to test it to ensure that it is unlocked. My AT&T GoPhone SIM card works, is that good enough?

    Yep. Borrow a friend's T-Mobile or Centennial SIM to double-check.

    I really can't think of anybody who has T-Mobile. But I do know somebody with Virgin mobile. Do they have SIM cards in them?

    It's been a couple of years since I've had a Virgin Mobile phone, but it didn't take SIM cards. Come to think of it I don't even know if GSM was around then....

    I don't think so. Virgin Mobile uses T-Mobile in the UK, but in the United States, they use Sprint's network. So that's CMDA.

    if you don't even know anybody on any other network does it really matter if its locked to at&t anyways?
