I currently have a 3g jailbroken iphone running OS 2.0.1. My question is that when I upgrade to 2.0.2 and jailbreak it, will I lose all of my apps and settings? I know that I can backup before and restore all of my app store apps (along with contacts, mail, etc.). But, will I loose all of the apps I have downloaded from cydia? Will I also loose my themes, NES games, and all the stuff that I have put on since jailbreaking it originally? Any help would be great, thank you.
