hey everyone who might read this
so i am currently running 4.0 on an itouch 3g and i used jailbrakeme.com to jailbrake (dont know if that matters) but i want to upgrade to 4.1 and re-jailbrake later
normaly i wouldnt care about doing this but i do have a few paid apps from cydia and apps that store data that i do not want to lose
how can i backup these apps?

thanks!

and if this is in the wrong place can a mod please move it
