BlackBerry Bold 9900 appears in leaked T-Mo docs, reveals August 29th release date and $300 price

If you're an abiding RIM fan who's itching for a new 'Berry addiction, your next fix is soon at hand. After AT&T put its cards on the table -- along with Sprint and US Cellular -- an internal T-Mobile document now suggests the Bold 9900 will arrive at the Magenta-clad carrier on August 29th. Sadly, your patience (and loyalty) is going to cost you, because this touchscreen endeavor carries a $300 price tag, and like Ma Bell's model, it features only 14.4Mbps HSDPA. Sure it's steep, but that's all the better for expensing to the corporate account, no?
