u can check mdelper from erica sadun on ericasadun.com. it extracts the file from your backup. but this app is Mac exclusive.

but if u wanna retrieve your file directly from the deleted parts on your iPhone flash memory (by imaging the iPhone drive), u can use dd utility via command line and transfer the file through SSH. for this it's a very time consuming work that by just extracting the whole iphone drive image it will take approx. 3 hours. for this u have to make sure u have Terminal, Installer and BSD / Unix Subsystem (this can't be done under Cydia).

happy recovering and good luck!

(i've just finished imaging my iPhone drive and performed recovery. finally!)
