I have Google set-up through Exchange and the Mail and Contacts work perfectly! I have a question about the Calendar though - is there a way to sync your Calendar through the Exchange have it able to to do more than one Alert? On the normal iPhone calendar you can, but as soon as you have that Exchange sync turned on, there is only the option of one alert. It would also be nice if Apple added the Email and Pop-Up options like Google offers!! Any suggestions though?
