I'm not entirely sure of the GMS I'm using. The installer said GMS 2, but help-->about says Version:

Anyways, we setup 1 device on the GMS, and it appears to be working fine. We tried to setup another device, it receives the SMS message, & installs the client ok. But when it tries to sync, the phone gets a "http error returned from webserver. (0x1008)" error. Also, the new device doesn't show up in the GMS.

We have an older version working previous to all of this, so I know these phones are supported and that it's capable of working.

Any help would be greatly appreciated.
