While window shopping online last night, we stumbled upon a new phone over at BestBuy.com. The HTC Touch Cruise is now being offered in the "unlocked" variety on the store's for $549.99. We liked this phone at the 2009 Mobile World Congress and it's nice to see it start to trickle into the U.S. Market. Best Buy is listing the Touch Cruise as back-ordered with expected shipping in 1 to 2 weeks. Could this be the start of the HTC summer invasion? Is the Touch Diamond 2 next?
