AT&T is now selling LG Quantum only for $0.01 and of course a two-year contract is required as well as a minimum data service starting at $15/month. Anyway it's a great deal!
The Quantum is one of very few QWERTY keyboard-equipped Windows Phone 7
device that also comes with Qualcomm’s 1GHz processor, 5-megapixel
camera with LED flash and HD video recording capability, 512MB of RAM,
16GB of built-in storage and DLNA support.
Quantum users also get free access to LG app store.
