Well sorry if there is already a post for these questions I have read several and most of them are different. 1. Can I jailbreak 3.1.3(tethered or untethered)? 2. Do I need to downgrade, and is that even possible since it needs signed firmware? 3. What program is the latest and will have the first 3.1.3 jailbreak? 4. What is the difference between this model and the 2nd gen if they have the same hardware? 5. I heard Jailbreak can make it slow and insecure, is that true? 6. What are the best features that you get from jailbreaking? 7. Will I still be able to buy and update all my purchased apps? Sorry if I sound like a noob, but I just got my ipod a little while ago. I am used to PSP's and DS's.
