    I bought iphone 3G (activated) from ebay and I clicked restore from itune.
    Then, it locked.
    It said "Insert an unlocked and valid SIM to activate iphone". :(

    Can I use my friend SIM card (AT&T not iphone plan) to activate at AT&T?

    if cannot

    I'm gonna buy new iphone 3G and let AT&T activate my new iphone.
    At this point, can I let them activate my old iphone 3G as well?

    The question is can they activate two iphone 3G by one AT&T number?
    The reason why I'm gonna do this because my old one was locked by restoring. After that, I'll have two iphone activated to use.


    Any suggestion for activation?
    Thanks

    You should be able to use any at&t SIM to activate the phone, but it may not work.

    As for the second part, The number is tied to the SIM, not the phone, so you could remove the SIM from an activated 3G iPhone, then insert it into the other and it should activate.

    Activate by myself but not only at at&t, right?

    As the 2nd part, do you mean I can activate the second iphone by myself at home since the first one has activated at at&t store, right?

    Are you sure?
    If it does so, I'll buy a new one.

    The SIM will already be active. Then when you insert it into the phone, it will search out the at&t signal (which it tries to do upon restore or upgrade), since the SIM is activated, it will find one, then the phone will be activated.
