I have received fw: 2.1-update1.
At first sight, the only noticable change is that I have 5 home sreens now as default. It can be set upto 9 screens.
New apps: Camcorder, All Videos, Facebook, Moto Car Home, Voice Dialer, (Help Centre, and Quickoffice icons I do not remember having before).
Thumbscrolling on webpages and menus improved a lot with the upgrade, it does not "overscroll" anymore. If you know what I mean.. I'm very happy about this, it greatly improves the overall usability of the phone!
Media Galery and Camera app is updated
