The August 2013 MFT 3.6.2 Sync update is out.
#17
Did the update this weekend. My phone connects almost immediately now and stays connected. The instructions tell you to make a note of your favorites on the Nav because they will be deleted. Mine were still there after the update. Also instructions state to plug thumb drive back in computer to confirm update, website shows update confirmed without this step. One enhancement I've noticed is with My Ford Touch in home position and the entertainment on it will show song and artist which it did not before.
