A new BlackBerry has popped up at the FCC. A device with 3G bands for AT&T and model number REA71UW is about all we know. AT&T is still due to launch the BlackBerry Curve 9360, and it might be likely to see the Bold 9790 hit the Blue carrier too. For now, BlackBerry REA71UW remains shrouded in mystery. Maybe if you dig a bit further through the SAR reports you might find more clues as to what this device could be. Check out the FCC filing here.
