Yes I recently jailbroke my iPod 2nd gen and all the apps I got off iTunes or the AppStore didn't get deleted
you won't get any more free apps and the things you used to have when you jailbroke it. You will also improve the speed your ipod works at and hopefully, the battery percentage will incease.
You hit the reset button.
To 'unjailbreak' an iPod Touch, you have to do a system restore, which is available in the iPod Touch home menu in iTunes. This will erase all content that is on the iPod Touch, including bookmarks in Safari and contacts in the Contacts.
Yes iTunes>(iPod Touch Name)>Restore
Yes, updating the software of an iPod undoes the Jailbreak.
All you have to do is just hit the reset button.
You cannot get all apps for free without jailbreaking an iPod Touch. It is not possible.
plug it into itunes and hit restore
You can't get apps wirelessly without wifi but you can plug your device into computer.
I've been told if you have ifile and you go to /Applications and delete all third party (jailbroken) apps and software then that will work. I'm not entirely sure I've never tried. That's what someone said on a forum. Good Luck ^_^.
You just buy only free apps.
