I have a Sony Ericsson T616 that I use with my 1.33GHz 12" PowerBook running OS X 10.4.1. I see this bug (and can reproduce it) with iCal: If I put the iSync in my menu bar I can no longer sync it with my phone (actually I can using the iSync within the Applications folder). Seems it works only with .Mac (which I don't have). If I click 'Sync Now' option it just goes and goes and... well it never ends. It looks like iSync just ignore my phone and keep trying to sync .Mac. Anyone else experiencing this!?
