I bought an unlocked Desire HD on the internet from a reputable dealer. Had trouble setting up mms so I phoned HTC, who told me the phone came from Germany (I live in Australia) & certain features might not work on this phone because it is set up for Germany (eg different radio frequencies). I got the mms problem sorted, but what do you think? Am I likely to have other unforeseen problems in future? Should I try to exchange it?
