If You Use Exhange And Recentlly Updated To 2.2 You May Have Noticed That Your Battery Life Was Shorter And Your iPhone Was Heating Up. If So The Reason For This Is Because The 2.2 Update Does Not Agree With Current Exchange Settings. The iPhone Keeps Searching For Mail instead of Waiting for it to be Recieved thru Push. 
To Fix This Just Delete Your Exchange Account And Then Set It Up Again From Scratch.
