Earlier today we heard that both Sprint and Verizon will offer an unlocked micro SIM in the iPhone 4S, which would allow you to use your iPhone 4S abroad with a GSM SIM card.
Now it would appear that this wont be the case from Sprint, and Sprint will instead support international roaming on GSM networks, which means you will probably end up having to pay high roaming fees when you use your iPhone 4S.
If Sprint had offered the unlocked micro SIM on the iPhone 4S then you would have been able to us a prepaid micro SIM card in your iPhone 4S when you go abroad.
Apple has now announced the iPhone 5, have a look at our article on the difference between the iPhone 4S and iPhone 5 to see all about the new iPhone 5.
