    Hello all,

    I just got the Iphone 4 and am not sure if I should activate it yet. Would it be possible to activate the Iphone 4 and use it now, and then say tomorrow switch back to my 3gs or would I need to be paying fees each time?

    I wanna use the new Iphone but really dont think I can live w/o my JB'd 3GS.

    thanks for the input.

    yeah, get a micro to minisim adapter for your microsim and you're good to go. All data plans are universal between 3G iPhones.
