Motorola's XT531 has gone through more name changes than a certain rapper-cum-vodka shilling mogul, and the trend might continue as it makes its way to the US. The budget-friendly handset, known as the Fire XT in Europe and the Spice XT in Latin America, has just surfaced at the FCC toting AT&T-compatible GSM bands, UMTS / HSDPA 850MHz / 1900MHz support, WiFi and Bluetooth. Based on Moto's official PR for the handset's Chinese release, we know this 3.5-incher also sports a front-facing VGA / 5 megapixel rear camera, and is set to launch with Android 2.3 onboard. With Google's newest pal clearly chasing after heat-related naming conventions, we expect to see this one launch with an equally caliente moniker.
