It is unlocked of course but it does not come with the box :(- im looking for a good swap such as; •Iphone 4/S, preferably unlocked and white but wouldnt mind a black one •Ipad 2/3 (no ipad 1) •Samsung galaxy S2 (white and unlocked) •HTC XL only •Sony ericsson xperia S (not arc s) *Please no blackberries what so ever and no windows phone- silly phones will be ignored!!* Also I am not interested in other tabs or consoles or laptops etc... Thanks
