Recently I got a gift from my relative and it is an iPhone 4S. However, it is in contract with Sprint Mobile . Can you please tell me how to unlock it?
Really interesting to see a major player become involved in iphone unlocking.
You can buy unlock code from EBAY,less than $10.

I have tried many, and all of them works fine.
you can also make request for the model you want to get unlock and that too... Free

Sprint locks iPhone 4S for international roaming -
This article says that in order to use other SIM,you need to have a good track record usage for 90 days i.e. paying bills,then you can contact them for unlocking it and use it for prepaid cards.
i believe sprint is part of the CDMA division. although it's a clean esn since it's new, i would have assumed you need the GSM (sim card) version of the phone.
