I'm trying to buy an iPhone 4s but was wondering if they ALL take sim cards.
My friend is offering me a CDMA iPhone but I am with T-Mobile (GSM Network).
Would I be able to use it on T-Mobile if I got the new sim card? I'm hearing mixed answers and would like to hear a straight answer.
Thank you so much!
