Has anyone ever bought devices from either of these vendors? If so, how was your experience in terms of purchasing, support, etc.? Also, are there any other sites/stores that sell unlocked 920's that I haven't mentioned here? I'm looking to use this on T-mobile here in the U.S. and various other carriers when I'm out of the country. From what I understand (and please correct me if I'm wrong because I'm trying to make an informed decision here), on T-mobile, these unlocked versions will only work on EDGE unless I'm in one of their newly refarmed areas. This isn't a huge factor for me since I have access to wifi almost everywhere I go. If there's anything else I should probably know and take into account, feel free to tell me. Last thing I need is to buy this thing and get screwed over. Thanks
