This might be a question already answered, but lately my iPod Touch's software has been acting up. It is jailbroken 1.1.1 and I've refrained from upgrading to 1.1.2 because of that. If I restore to 1.1.1 will it brick my iPod or is it a safe restore. Also, if my iPod does become bricked ever, will the Apple Store restore the software? Thanks.
