Cheap smartphones are getting more common, but the BLU Dash 4.5 is redefining the term budget. For $139, unlocked and unsubsidized, you can own an Android 4.2 Jelly Bean handset with a 1.2GHz quad-core chip from MediaTek, 512MB of RAM, 5-megapixel camera, 4.5-inch 854 x 480 pixel display and 21Mbps HSPA+ support for both AT&T and T-Mobile. Though it's not the thinnest device in the world at 11.9mm (0.47 inches) thick, we're willing to ignore that given the price tag. It's $10 cheaper than our current favorite budget smartphone, the Nokia Lumia 520, and you can buy it from Amazon today. We've found an unboxing video in Spanish -- if you're interested, it's just after the break.
