If rumors are to be believed, it seems that for about 2 weeks Walmart will be the exclusive carrier of T-Mobile’s BlackBerry Curve 8520 starting on August 5th.

For those who don’t know the BlackBerry 8520 features a 320 x 240 resolution display, 2MP camera, WiFi, quad-band GSM and RIM’s OS 5.0. Unfortunately, those looking for a 3G capable device will be discouraged to hear that this will not feature said connectivity.

Alternatively, if you want to grab one ahead of the competition you can always count on eBay.
