An internal document from AT&T might be considered confirmation of a launch date for the hot, new Motorola Atrix 4G. Considered one of the best Android-devices to be unveiled at last week’s CES, the phone looks to be arriving on Tuesday, March 1. However, as AndroidCentral notes, this may or may not be 100-percent certain as AT&T typically releases phones on Sunday. Pricing remains a mystery although we surmised on this Monday’s podcast that it may run somewhere in the $200-$249 ball park. Leaked document after the break.
