I must say that I've had a bit of a mixed experience with using activesync on my new (4 month old) Smartphone 3. It used to wait and not successfully connect to our frontend exchange servers on a semi-regular basis. I assumed it had something to do with QOS on the voice, and the lower priority of data traffic, until I discovered it was the way the phone was configured from the telco here in New Zealand. If you change the data connection (start/settings/more/data connections) for WAP from VFNZ Gateway (live.vodafone.com) to VFNZ Gateway (www.vodafone.net.nz, or the cname internet also works) the user experience is fantastically reliable! Phew!
