Along with the features on the phone like a calendar and a variety of ringers, there's a website that expands the feature set a bit, but doesn't go the distance. I can go to the website, add an appointment to the calendar there, and it will send me a notification (if I asked for one) on my phone. However, it won't send that to the calendar on the phone. Get the disconnect here?
The phone and the website do not synch. This makes any management done on one side necessary on the other. For that reason, I wish I was able to get a SonyErricson with Bluetooth support so I could keep it up to date from my Mac. Cool ringers are cool, but convergence (aka, convenience) owns.
