I have a 7520 and have had nothing but problems... It messed up my iCal and address book... I wish there was a way to control the way it syncs... I.E. BBerry to Mac, Mac to BBerry, and two-way... I wish I could start clean on my Mac and have my iCal imported from the BBerry as well as the address book... I am using Tiger with the latest PocketMac update... Anyone know how to do this and clean out my address book on my Mac to start fresh???
