Update: Motorola has announced that all Nexus 6 devices should be able to be activated on Sprint now. People are reporting successful activation of Motorola-purchased devices, and I was personally able to activate my AT&T Nexus 6 on Sprint by simply calling Sprint, giving them the MEID (IMEI minus the last digit) and the SIM card number I wanted to use. The device shows up under my account as a Nexus 6 and appears to be working beautifully.
