I now have a 7610 too. And I am using it mostly for business.
Active Today and Agile Messenger after downloaded the upgrade work perfect. However I would like to de-install some of the apps that are pre-installed such as Facewave or the Welcome SW etc. etc.. The goal is to free up memory of course.
Whenever I go inthe Application Manager to de-install, I get a quick message: Childinstaller closed. And the Application Manager removing bar freezes.
