I've had no problems getting my Moto Droid to pair on first go. address book downloaded, but what I've seen is that while my phone said "other/mobile", Sync will have problems w/the phone# to list it as "mobile" and you need to say "other". I fixed this by going back up into Google addressbook, setting the phone# type to MOBILE, and then resync my addr book to my phone & then to my Edge. works now!
