MetroPCS is adding the LG Motion 4G smartphone to its stables today. Spotted in a leak last month, the phone is the carrier's first smartphone to run Android 4.0 Ice Cream Sandwich. In addition to running on Metro's 4G LTE network, the Motion 4G also supports the carrier's voice over LTE (VoLTE) services. It is powered by a dual-core 1.2GHz processor and comes with a 5-megapixel camera that can capture 1080p HD video. Users can play with LG's QuickMemo app on the 3.5-inch Gorilla Glass display, as well as snap photos with the sound of their voices (LG calls this feature "Cheese Shot").

In addition to the new phone, MetroPCS is also unveiling a new, lower-cost unlimited plan that will be available for a limited time. Single line customers can get unlimited talk, text, and data services for $55 per month — a savings of $15 per month over Metro's prior offerings — while family plan customers can get the same features on their second, third, and fourth lines for $50 per month per line. The carrier did not say for how long the promotional pricing will be available, but customers that sign a two-year agreement with it now will have the lower price for the length of their contract.

Those interested can pick up the LG Motion 4G from MetroPCS in stores and online for $149 with a new two-year contract now.
