Motorola's Atrix and Xoom might reach Sprint as their second US carrier and may not have long to wait, a rumor maintained Thursday. Sprint would reportedly get WiMAX versions of both Android devices in an April introduction, including the Lapdock add-on. The Android and Me source has been accurate in the past and suggested the names might change, both to differentiate the Atrix and for the Xoom to avoid more trademark issues.
