    Hi!

    So, I've been limping along on my 3G waiting for the 4 to come out. I'm stoked to get a new phone and this should really be a nice upgrade for me.

    Question though... will the sim from my 3g work in the 4? For example, if I pick up my new iphone on the 24th will my phone leave the store ready to go with all the info from my 3G? Or will I need to go home and sync it with itunes before I get all my phone numbers loaded in and such? Thanks!

    iPhone 4 uses Micro sim which is smaller then the old sim cards. So your old 3g sim will not work. Like you mentioned you just sync your info at home.

    you will get a new Micro Sim, your old sim will be de activated from your number..

    numbers are saved to the iPhone, backup your old phone, restore onto your new phone

    You will have to sync.

    Did mine last night. Needed a restore too (as others have also reported).
