Jailbreak question thanks?

-When u jailbreak does all ur old apps that u bought disappear? I spent 40$ ahahaha

Can ur itouch brick (means turn useless) when u jailbreak?

Thank you (:The apps that you bought stay (unless you restore your itouch) & yea you can brick your phone, but that can be avoided. make sure what firmware your iPod is running on & jailbreak it through a program that supports the firmware.(for example your iPod is 4.2.1 and you jailbroke it through a program for 4.3 ends up in bricking it)Your legit apps stay and yes it is possible to Brick your device if you mess up the JB but only retards mess up.
