Please can anyone provide any help or guidance about getting. Sprint 4S unlocked? My wife had a two year contract that has just ended, and we have asked Sprint to unlock her phone for both international and domestic use. They provided an unlock code (that they call an MSL) and said the new provider would be able to use it. Unfortunately everyone we have contacted, including Apple and some third party unlockers, have all said that only Sprint can unlock it, and Sprint keep insisting that they can't. It feels like we're being given the run-around and could really do with some pointers!!
