Ok here is the scoop directly from Expansys. This is a UK version of the phone UNLOCKED.. You will receive Tom Tom GPS mapping software (remember you can pick one city and then you have to purchase whatever other maps you want) now I cannot confirm the Tom Tom maps are for US. From my conversations with expansys these maps are for UK only. That doesn’t mean you cant load Pharos, Delorme or any other GPS software on this unit. So you can use your own judgement. Also the price is higher because this unit IS unlocked.
