    odd question I'm sure..

    if I was using the sim in another device, would I run into problems doing a restore and activate without the sim present?

    I seem to remember running into that before on an iphone 2G...

    Another question along those same lines, could I use an inactive sim in it's place for a restore? I know this works on my 3G, I restore it all the time and just use an old AT&T sim that doesn't have service to keep it happy..

    Thanks.

    Yeah you can restore it with an AT&T sim card even if it's not active. Or even if you have to borrow
    someone's active sim card.

    With inactive sim card, you can restore iphone 4.

    Thanks guys!

    I've got an extra sim card on the way and a micro sim adapter so I can use my active sim in my iphone 3G while I restore my iphone 4.

    I'll tether to the 3G to my laptop while I restore. (No internet at my house right now)

    It's a bit of a hack, but I think it'll work, and it's better than trying to borrow my wife's sim card..

    You can restore an iPhone without a sim at all too. I do it all the time with my 3GS as my sim is never even there and I only use it for testing. It won't activate but it'll restore just fine and you can use it as an iPod after. It won't freeze or fail.

    Thanks, I do that too with my old 3G, but I need the iphone 4 to activate.. which is why I need the tethered internet connection from the other phone.. (Normally I drive into town and activate in the starbucks parking lot on their wifi, lol)

    I did have a problem with an iphone 2g that I could not for the life of me get it to restore without a sim. I thought it was dead for about a week...
