remove jailbreak without losing data? (having some trouble with last jb:) )

[neonkru]

Hello. I jailbreaked my device yesterday using the new RC1 release for ios 4.1. I wanted to try out some apps before buying them but i feel the device sometimes slower and sometimes apps quit for no reason. Happened in both jailbreaked apps and purchased apps. so i want to revert to original (mine shipped with ios 4.1), if i hit restore will i lose my that? like saved games and installed apps?

thank you in advance

If you restore from a backup all your data will be there. However if you want Apple to not be able to tell that you jail broke you need to do a fresh restore.

What apps were running slow or quitting? I have not had that experience.

Using pirated apps usually messes up your phone. Why don't you uninstall these apps and see how your phone works.
