If you go to www.macenterprise.org there should be a link to the latest web cast that JAMF put on where they demonstrated all the stuff you can do with the iPhone. I was working while watching it so I didn't get to see the whole thing and I think you can still download the video. Probably answer all your questions.
Another user was kind enough to send me the following information which
I'll share. This is unsupported but apparently functional.
"I have done some very brief, and very unscientific testing, and the JSS
Mobile iPhone app seems to work with The Casper Suite version 7."
"Again, this is just one person's observation."
"The app can be found here... (link opens iTunes store)"
