Can it be recovered - looking for a data recovery program

[kyuukisan]

Any help is appreciated. I made a dummy move and left my phone unattened around some one I trusted and for whatever reason (hatred) they deleted some files that were on my phone. If anyone know of a program that will let me "un-delete " my phones hard drive I would love to know what it is. Also I'm having power issues with my device. Tell me what you think. I charge the phone and all of the programs that I run run for hours but when I use the phone it's as if the battery police are kicking down the door. I think I need a new battery. I just flashed to WM 6.1. Thanks for all help.
