If you really want to get your hands on an HTC Touch Diamond before the official US launch, CompUSA has one available for $779. The good news is that it's unlocked, so you can use it on both AT&T and T-Mobile, and quad-band, so you can take it just about anywhere where GSM goes. It's a nice phone, though kinda slow in our first impressions. Might want to wait until some more reviews hit before making your decision. [CompUSA]
@smokeonit: Amazingly not everyone in the world wants an iPhone. There are still some people left who prefer Windows Mobile. And anyone comparing this price to the price of the 3G iPhone isn't playing fair. This price is commitment free. The previous top of the line HTC phone ended up at AT&T for as low as $100.
This CompUSA price is just for people who really really want the phone NOW, and don't want to wait for an operator version. I did this with the TyTN; really wanted it, and paid $799 for it at the local dealer. It's all a question of what you want in a phone.
In this case I would not buy it, simply because it lacks 3G support for the US.
