I updated 1.0.0.30 on top of 10.0.0.29 and when I clicked on the home screen my BB would freeze.. so I uninstalled the app but the icon remained, clicking on it would freeze my BB... so after another battery pull I verified App World was not listed in my applications list re-installed 1.0.0.30 and its worked fine since.

Moral.. Uninstall the current version installed and then install the newest release

Or did I just have an odd ball situation?
