I have an iphone 3G and will soon get my sisters 3Gs (she is upgrading). i want to transfer all my information from my iphone to this new one. I know that itunes is probably the easiest way, but my current iphone isnt synced to my computer and cant be as it is synced to another which has been thrown out.can i simply put my sim card from my old iphone into the new one? will this transfer all the information? also, if i succeed in doing this, will this new combination of sim card and iphone 3Gs sync to my computer, which has no device synced to it?
