To me the SYNC looks much nicer than either of these phone. And besides being more aesthetically pleasing, the Sync also benefits from a better key pad and better directional pad as well. Also, the at&t branded SYNC was updated to support Video Share as well (the Cingular SYNC will not). All in all, the SYNC and the A717 operate exactly the same. And with the available external music keys, better key pad & better directional pad, I'll stick w/ the SYNC. And BTW, its like $100 cheaper.
