HTC 8X $250 unlocked
Not sure if this has been mentioned before or not, but Microsoft is selling the unlocked HTC 8X for just $250.
It's not Lumia 520 cheap, but we are talking about last year's flagship from HTC with 720p SLCD screen, gorilla glass, 16GB storage, 1GB RAM, 1.5GHz dual core krait, and LTE. Imo this is not a bad deal. Comparable Android handsets at this price range (excluding used and Nexus) have either outdated internals, 8GB storage, and/or lower res screen.
Only one color though, the bluish purple.
I wish Microsoft would start doing the same thing on Nokia's lineup.
