CompUSA is currently selling unlocked HTC Touch Diamond for $779. Unlocked means, you don’t have to sign any contract with any carrier and this phone can be used on any network where you provide your own SIM Card. Since you are not signing any long term contract with any carrier, you don’t receive any subsidy which explains the high price. But, if you have to have this phone right away and your carrier is currently not offering it, spend the $779 to be the first one to own this beautiful iPhone Killer.
