I am thinking of moving from a BB 9700 to the captivate and I have afew questions. I am going to access Gmail via IMAP. How fast is it and is it true IMAP? Does the calendar and contacts sync with Google instantly? What is the real life expectation of the battery after without streaming of video or audio? Does it offer the free turn by turn GPS from google? Same as the Droid? If not, how is ATT's branded GPS on it? Can the icons on the bottom dock be customized? Is there anything I need to know coming from a BB?
