Now that 3.1 network edition is almost here "Goal is later this week" (from previous post) -- what are the wireless capabilities for 3.1?

Will it work with blackberry devices? Does it require the use of blackberry enterprise server or will zimbra have integrated wireless push features?

What about a mobile access like MS Outlook Mobile access? Does Zimbra 3.1 have anything like a watered down webUI optimized for mobile devices?
