why is my ipod touch 4g crashing on iTunes, the appstore and safari? i never damaged my ipod and i kept it in good condition

When I recently updated to iOS 6 I noticed that my ipod was crashing more than usual, especialy on the App Store and Itunes. Then safari started crashing when I updated to iOS 6.01. I have had my ipod for almost a year now and it has been taken well care of, and has never been dropped. I just want to know if this can be fixed or will i have to spend $300 on a new ipod. Please answer
