Is it possible to backup an iPhone without the SIM card?
I've been an iPhone 3G user until recently when I bought my unlocked iPhone 4S. I was informed that I need to get my SIM card clipped in order for it to fit the new phone. My situation is that I'm actually traveling in overseas at the moment and do not have my computer with me to backup my old iPhone 3G. So my question is: can I go ahead and clip my SIM card now and then backup my iPhone 3G later without any SIM card, and finally syncing my new iPhone 4S? Or must I have my SIM card in the old iPhone 3G while backing it up?
