2 part question

1. Does anyone know for GroupWise Mobile Server, if a data connection is a
must for the client. I know there is both a network push and SMS push, but
I would think that it would be required to have a data connection for a 2
way sync. Can anyone verify this ?

2. Are there release notes by chance for SP2 for GroupWise Mobile 2. I'm
trying to figure out how to get notified when these come out and if I need
them but I don't know where Groupwise Mobile is ever mentioned in the
install. All i ever see is the Intellisync versions which dont correlate.

I would appreciate any help.
