We've seen leaked shots here and there, but it's always nice when products get the official "go ahead" (and cuts down on potentially false rumors, to boot).  In a press release this morning, T-Mobile officially announced the BlackBerry Curve 8520, launching on August 5th for $129.99 with a new two-year agreement.  Important specifications include a 512 MHz processor with 256 MB of memory, optical trackpad, Bluetooth 2.0, a 2 megapixel camera, 3.5 mm headphone jack, Wi-Fi 802.11 b/g for compatibility with T-Mobile's Hotspot calling service, microSD card slot with a 1 GB card included, and EGDE/GPRS/GSM (850/900/1800/1900 MHz) support.  In an interesting twist (and finally, support for the "other" BlackBerry users out there), the 8520 is listed with "out of the box Mac compatibility."

Breaking original rumors that the device was a Walmart exclusive, the Curve 8520 will be available at T-Mobile retail stores, Walmart locations, select authorized dealers, and T-Mobile's website.
