And on the G1, you had to pay $30 for TouchDown to sync with MS Exchange.

Seriously dude. You have an axe to grind with Nokia. You refuse to state how much research you yourself have done; I didn't see provisioning on any documents, knowing Nokia... I would have assumed it didn't do it.

And as of yet, I have yet to purchase a N900. If MS Exchange is that important, picking up the phone and calling Nokia would have proven prudent to you.

Good luck. I can state that the iPhone 3GS does exactly as you'll need pertaining provisioning and MS Exchange.

I'll remove myself from this thread since you'll likely not see fault in any actions other than Nokia - which is understandable - and continue to act as such where others are trying to offer help.

Luck to you.
