I'm considering moving from my 2.1 rooted to one of the recently released 2.2 builds. As is suggested, I plan on resetting my phone (aka, wiping) before installing 2.2. Anyhow, there are a few programs with a lot of configuration options that I would like to not have to manually re-do. Is there a way to backup the settings for specific applications, and restore them after the apps have been automatically restored?
