hello alice i had the same problem. to solve it i had to backup my phone on a pc (you can not do a complet backup on a mac). if you don't have to many settings you don't need to back up. then i did a master reset: controll panel, other, master reset (if you have not set a password for your phone yet, the standard password is 0000). Carefull! this deletes everything on your phone setting it back in its "newly born" state. after this i was able to sync my phone with isync. although i have allways to turn on bluetooth, turn the phone off and turn it on again. hope that helps greetings from very cold switzerland marcel
