got my iphone, my notifylink and groupwise all working as billed. I phone 3G battery life sucks, but just turn off 3G and that solves that. Contacts Calendar and email syncing no problems. Quite a bit slower on the push compared to GMS and Treo, but the people who want iphones in my office are not admins and they wont care about that.

Thank you notify link for that... I fear my users would have demanded exchange if they did not get iphone support for groupwise.

I am using On Demand hosted notify link at the moment so that might also be adding to the slowness, but the Notify tech support has been awesome so far.
