iPhone 2.0 Software - Push

Everybody knows that iPhone 2.0 software supports Microsoft Exchange ActiveSync. But the devil details are as follows (based on my experience):
  • Exchange email & calendaring works beautifully - just like the preview videos Apple showed and like BlackBerry and ActiveSync users have been enjoying for a while. And setup is a breeze using the iPhone Configuration Utility. It does feel a bit strange to email the config file instead of just dowloading it to an attached iPhone. But it'll work well for enterprise users - "one profile to rule them all".
  • Cisco VPN setup with Group authentication is a bit awkward.
  • If you get a lot of emails, like 1 every 5 minutes, because someone put you on a jillion lists then enabling 'Push' will drain your iPhone's battery enough to require daily charging even with minimum use. Plus your phone vibrates every 5 seconds and makes you look like a twitching retard. Use Fetch with settings of 15 min, 30 min or 1 hour - depending on how desperate you are.
  • Someone tells me that there are specific push-related rules, i.e. set a rule to determine which email messages get pushed. But apparently it is only available, for setting, through Outlook. I use a Mac and checked Outlook Web Access using IE on Windows XP under Fusion, but could not find it. Need more research!

  • Below are relevant documents & links on the subject.
