Like after you do a Hard Reset, you need to go back and get your data? No, I believe all your data is lost forever... I know you can use Active Sync to back up your data before hand so it is stored on your computer... This is the link to Active Sync...

I know there are programs out there for backing up your data... But I know of no data recovery programs... Sorry for your loss....
