No, I jailbroke my iPod touch with blackra1n, and I didnt have to restore it.

Yes. But if it is tethered, you will have to use the program you jailbroke it with to reboot it. This will not erase anything on your iTouch.
no.
No.
As long as you fully remove the jailbreak by doing a factory reset, yes. Otherwise, the store you are trying to trade it in to may not accept it.
it's like hacking an ipod, everyting is free on a jailbroken ipod, BUT IT'S ILEGAL!! there are like 450 free awsome apps on the ipod touch! DON'T JAILBREAK UR IPOD! and if u do want to, search utube, 1000000vids will come up......
Yes. I jailbroke my iPod touch using green pois0n RC6 and all of my apps stayed on my iPod.
No
You download cydia, which is where you are able to get most of the themes or applications that will further your customization with your ipod. How you get this is very simple if you use blackra1n, and you can experience that by checking on youtube.
Yes I recently jailbroke my iPod 2nd gen and all the apps I got off iTunes or the AppStore didn't get deleted
no you can't. you can't buy any fonts on iPod touch. It is not on iTunes. You can download new fonts for anything on all G's of ipods if you have it jailbroke.
