Hi there, (Long time lurker, first time poster here). I have an iPhone 5 which was gifted to me by an American friend who works for Apple in the US. I live in the UK but didn't open it for 6 months because I was super busy with work. I opened it recently to find a Sprint sim card inside. I've read here and elsewhere that it can be unlocked for foreign use - any tips? The furthest I've got is that I can bypass the need to activate it with a GPP sim, which then leaves me open to unlock it (somehow). Any help would be massively appreciated. Thanks.
