BLU Products' unlocked smartphones have only been truly useful in North America when using bigger carriers like AT&T and Rogers, but the company is giving us a few more choices today. Its new Advance 4.0 and Studio 5.0 II both support HSPA+ data on smaller networks like T-Mobile, Solavei and Wind Mobile; if you want to jump to a cheaper provider, you won't have to give up 3G in the process. The handsets are otherwise modest. Both Android 4.2 devices come with a dual-core 1.3GHz MediaTek processor, 512MB of RAM, 4GB of expandable storage, a 5-megapixel rear camera and a front VGA camera. You're mostly left deciding between the Advance 4.0's 4-inch TFT display and the Studio 5.0 II's 5-inch IPS panel. Whichever phone you choose, it won't cost much. BLU is offering the Advance 4.0 today for $89 outright, while its Studio 5.0 II cousin sells for $139.
