    I'll soon be upgrading from an old iPhone 2G to the new iPhone 4.

    My 7 year old son would LOVE to be able to use my "dead" iPhone after it's been disconnected from my AT&T account.

    Is this possible? Would he be able to use it as a WiFi only device?

    Thanks...

    So, can it be still be plugged into iTunes? Can any apps be added and/or updated? Or no?

    I'm not really sure how this works, obviously. :eek:

    Yes it can. Just turn to airplane mode which turns off the cell radios. You can still turn on wifi and use it as a ipod touch. I do this with my old 3G.

    it will work just like an iPod touch. You will be able to add/delete all media without any issues.

    if for some reason you need to restore your Original iPhone firmware, it will need to have a Sim card to be activated with iTunes (you could use an old deactivate sim card), all it needs is to have a Sim card in the Sim tray.

    Excellent. Thanks.

    In that case, how do you use more than one iPhone with iTunes? I'll have one new iPhone 4 plus the old iPhone 2G.

    Come to think of it, if the phone has no service (shut off by AT&T) is it even necessary to turn on the Airplane mode?

    No, you don't need airplane mode. It's better than an iPod touch because you can make skill calls through wifi

    I'm thinking it might improve your battery life if you did.

    The plot thickens: My wife now wants an iPhone 4 also. So we'll have 3 iPhones on one iTunes account.

    There's a switch for "No cellular data" On or Off in settings.

    I have IP4, 3GS, 2G (no service) and IPod Touch 2G without any issue on same computer / iTunes.

    And, just keep 2G on airplane mode (saves battery?), but no service is OK too.

    This. My 3GS gets much better battery life in Airplane mode then with the old deactivated SIM in it. Just be sure to keep that SIM for restoring

    Thanks. I wasn't sure if AT&T took the SIM upon de-activation or left it alone.

    EDIT: On second thought, won't they just move the SIM chip from my old 2G iPhone to the new iPhone 4 ?

    Different SIM sizes--the ip4 uses a smaller one.

    Different size, but easily trimmed :)
