The 2009 version won't work for the 2010 competition since the scoring format is different. It will continue to work as a reference to see how teams did last year and it won't be confused by any 2010 data appearing on Twitter, etc.
I hope to release a new version of the 2009 app to Apple in the next week or so with some new features I've been working on, including team robot photos from TBA and ranking teams by OPR and DPR.
There will be a 2010 version of FRC Tracker, a different app so you can have one or both on your device. My hope is to get that submitted to Apple in time to be available for the first weekend of regionals.
As for getting the app running on other platforms, I'm buried in iPhone work and don't have an interest in learning Windows Mobile or Android. The code for FRC Tracker is about 99% user interface code specific to the iPhone platform that would be of no use on the other platforms. I even use an iPhone API to parse Twitter's XML. The most interesting code that's not platform-specific is the OPR/DPR calculation, but that's already well documented on the forum.
If anyone developing a similar app on another platform has any specific questions about how to do something, feel free to send me a direct message.
You can follow progress on the new versions via
