    I recently purchased an unlocked iPhone from the Marketplace, and I had a question to ask in regards to testing it out.

    The seller had the iPhone unlocked by AT&T. Now, without a Sim in the phone, the iPhone asks (when connected to iTunes or not) to "Insert a Valid Sim card". I wanted to go through the phone and test it all out, but all I have are AT&T and Straight Talk Sims.

    My family member that's getting it wants to use it on T-Mobile. Can I activate it with one of my Sims to start, or will that lock it to a carrier and prevent her from using her T-Mobile Sim when she gets it?

    If the phone is unlocked, just pop in any sim. It will not lock to that carrier.
