So I do a fair amount of overseas travel and have never had an issue using my iphone and getting 3G speeds on the internet. I have also bought unlocked GSM phones and have not had an issu e either. I'm in the UK now and the Desire HD is coming out next week and I'm wondering why I can't just buy it and use it fine when I come back to the US. Presumably if I were a UK resident and travelled to the US with this phone it would work fine just as I'm able to do with my US-based iphone in the UK. I understand every carrier and region uses its own frequencies but I don't understand why I'd be able to travel and get 3G speeds overseas but the concept of bring a phone over from another country but being stuck with 2G or Edge internet speeds doesn't click for me. Can someone clear this up?
