Important Notes:
There is a second maintenance release available for those New EVOs purchased (starting sometime in November). The newly manufactured EVOs are using a different manufacturer's part and software version 3.30.651.2 (released on 11/4). All EVOs on software version 3.30.651.2 should apply this new second maintenance release 3.30.651.3.
Sofware version 3.30.651.3 is not required for all EVOs and will not be distributed to those not utilizing the new manufacturer's part. If your device was purchased previous to November and is on version 3.29.651.5, your software is considered current.
