It has been a busy day for RIM. After the announcement of BlackBerry OS 7, which will be running on the new BlackBerry Bold 9900 and 9930, we’re now hearing from T-Mobile that the Bold 9900 will be available, with 4G HSPA+ enabled, at some point this year. Pricing is likely to be around $199.99. The BlackBerry Bold 9900 features a pretty impressive spec sheet with a 1.2GHz single-core CPU with 768MB of RAM, a 2.8″ VGA touchscreen display, 720p video recording, and 8GB of onboard storage. The BlackBerry Bold 9900 is RIM’s thinnest yet at 10.5mm.
