The iPhone makes pretty decent use of its gravity sensor with Safari, but that’s something of a kid’s trick compared to the WND DUO Atom, which flips between two SIM cards as you flip it from top to bottom (or is it bottom to top?), making it easy to maintain two separate accounts. Like one for wife, one for your girlfriend—just don’t turn it the wrong way. It’s also a touchscreener, so the keypad and screen re-orient themselves accordingly. Hit the jump for the nitty-gritty and another glamour shot of this unlocked tri-band GSM trickster.
