Apple help with all of apps after jailbreak

[pokeman138]

I got my Ipod touch and I jailbroke with 4.1 and I do not want to lose me save files
I worked really hard on Asphalt 5 is there a way I can take the saves with me when iOS 4.2 comes out

I believe there's a save backup somewhere on Cydia. Unfortunately I can't remember its name

When 4.2 comes out restoring from backup should be enough though. All your saves and settings are backed up by iTunes automatically

To save your Cydia apps, you need APTbackup.
For other stuff (like save files) you can either save them manually through SSH, backup your iPod in iTunes or just update your iPod, and not restore it. (updating keeps personal files)
