I guess I was reading betwen the lines when I read this off the VZW Why to upgrade and 4.0 features
[SNIP] Wireless Provisioning:
IT Administrators can quickly and securely provision end user devices wirelessly so users can start using their BlackBerry faster than ever.
To me that implies I need not get the employees to upgrade their own systems ... Also I upgrade one of the 7750's thru the desktop manager and tried to provision it wirelessly .... with the upgrade there was no Enterprise Activation
under options or on the desktop ... I put off RTFM'ng the BES manual till tomorrow ... if it gives me the answers I'll make sure to update the thread ....
