Have you been looking to get your hands on a nice slice of Gingerbread without totally wrecking your wallet? If so your time has come. Best Buy has announced that starting tonight (August 2nd) at 11 p.m. CST -- we'll assume they meant CDT, aka midnight Eastern -- it will begin offering the Google Nexus S for free (you read that right). Of course, you'll still have to chain yourself to a two-year agreement with AT&T or T-Mobile to cash in on this deal, but wait a day
