Hi Everyone, I am currently using an iPhone, however I am planning on switching over to the Galaxy Nexus when it is released. I am thinking about importing an unlocked one, and then using it on AT&T. However, I have a few question. Firstly, if I'm importing one from the UK (HSPA+ of course), will I be able to put in an AT&T sim card into my phone and get full functionality of it (i.e. internet, phone, texting, voicemail, etc)-- in addition will AT&T be able to provide a sim card for it? Also, are there any big differences between buying a UK one and a US one (like Android Market differences, missing features, etc)? Thanks a bunch in advance everyone!
