How are they tracking unique activations? IMEI numbers seems the most likely possibility to me, but I wouldn't think Google would keep a list of all the numbers on their servers.

IMEI most likely. They can transmit the number as a non-reversible hash (MD5 or similar), that way the number never gets sent or stored as plain text.
