One thing I would probably add to this review which I started writing a few weeks ago is ONE MAJOR DISADVANTAGE of the iPhone if you plan on using ActiveSync. When you reply to a message on your iPhone, Outlook only shows that the message has been read and the Outlook sent folder contains a copy of the sent message. This is really not suitable for someone like me who relies on their phone to send/reply to emails. It is difficult to remember whether I have sent emails or just read them by the end of the day so its a major inconvenience.
If anyone knows whether a solution has been found, then that would be incredibly helpful. Otherwise, switch phones are your own peril. The iPhone is a great device but it hasn't been able to match the Blackberry in the email area.
If you're planning on going back to a BIS type BB account, you will actually get less functionality then you had with Active Sync. No folder sync, no contact or calendar sync. The only way to get this with BB is to be on a BES account. BES is the only way the BB is superior to the iphone with email.
