Will a Sprint iPhone 4S work on T-Mobile?

My friend is sending me down a iPhone 4S later in the week, and I want to know if its even worth taking to get unlocked to work for my carrier (T-Mobile). The iPhone 4S isn't factory unlocked or anything. Its just a regular iPhone from Sprint. Can someone please help and tell me what I can do to make work on T-Mobile.

You can't make it work. T-mobile requires a SIM-card while sprint is CDMA which means the code is inside the phone, A sprint iphone is not compatible with T-mobile network.
