Credo Mobile offers free phones, $350 bill credit for new customers

Sprint mobile virtual network operator Credo Mobile, a carrier that is also a progressive activism movement, is offering any of there phones for free, along with $350 to cover an early cancellation fee on your current network.
There phone selection isn't that great, though they do have the Samsung Galaxy S III, and there plans will cost you about the same as AT&T or Verizon while riding on Sprint's slow, sparse network, but if you want your bill to go to a variety of progressive causes this is your only choice.
