hello, I have a first ten iPod touch, before the 2.1 update my iPod was jailbroken. Once the update came out, a friend of mine told me that if I tried to get this update on a jailbroken iPod my iPod would get corrupted. I recently came back to this form to see that people have jailbroken a 2.1 iPod, so I have some questions. If I jailbreak my 2.1 iPod, can I still use all my purchased apps and will the app store be fully functional. Also, when feature firmware updates for the iPod touch are released can I download these or will I have to wait till someone finds some hack to ensure nothing will get corrupted.
