Synchronization is not reliable.
Originally, I thought this was going to be the solution for a person who is a heavy Tasks user that must sync with Exchange. I sure was wrong. Just not reliable enough and very slow. Had the iPhone 4 for a month and have switched to the Blackberry Torch. The Torch is the best "Enterprise" smartphone going and works perfectly with Exchange. The iPhone is fine "consumer" phone, but it cannot work reliably in the business world if you need all 5 categories in Exchange to sync perfectly and quickly.
