Well my galaxy s2s lock button will work wen it wants to and I want to take it back and just get a iphone but my sprint plan isn't up till coming march Is there anyway I can fix it and how much would it cost to just replace it with an iphone

If you have to get another phone before you are ready for an upgrade, you will either have to pay Sprint full retail price for it ($400-$650 or more depending on which one you want), or buy a used one on eBay etc.

If you buy a used one, it has to be a Sprint iPhone; iPhones for other carriers (AT&T, Verizon, etc.) won't work. And it also has to have a "clean ESN" which means it hasn't been blocked because it was lost or stolen or had an unpaid bill.
