Well, there's a lot of good stuff on it, including the latest OS2008 version and cumbersome Wayfinder map-downloads that I'm fine with keeping. It took me 5 hours to get the Eastern U.S. map. Nokia has reduced their support for the N810 and for me it's not worth the potential re-installation hassles right now. You can't even download Skype for it anymore (officially). I may reformat it in the future but I'm looking for a specific answer to this question at the moment. Thanks.
