Sort of works on my blackberry curve 8900. I can login and get contacts to sync. Last time I tried it a month or so ago it was doing bad things. E.g., deleting a contact via the web would pull the, now missing contact, from the phone and vice versa which was very lame. Saw some unconfirmed funny business with the calendar and decided to uninstall it. The one thing it did that I liked was chew up more bandwidth. With ridiculously high unlimited data rates I try to get my moneys worth!
