Sprint is running some specials of its own for the Black Friday shopping frenzy, as it has announced that the Google Nexus S 4G and the Samsung Conquer 4G will be free with a new two-year contract during the weekend after Thanksgiving. The Nexus S 4G will be available in store and online, while the Conquer 4G will be an online-only special. Sprint is also among the retailers slashing the price of the 16GB BlackBerry PlayBook down to $199 for the weekend.
