yes you get this cool thing called cydia which lets you get cool things for your i device but you need to make sure you have a firmware that has an untethered jailbreak and you need to add sources to get more apps from cydia.
You can basically get free apps and get cool springboards.
One awesome IPod Touch/ IPhone app is Jelly Car.
You can't, Jailbreaking is cool. Why do you want to take it off. Well just restore it! If you take cydia and stufff off you'll take off your jailbreak and ya. ENJOY!
Jailbreaking is pretty much like unlocking your ipod. There are lots of cool things you can do when you jailbreak that the regular Apple firmware doesn't allow. When you jailbreak usually you will get a new app-store equivalent called cydia. This is where you get new apps not allowed on the regular app store.
you just go to settings hit password
To listen to music and to also use loads of cool apps that can be downloaded.
If you like music and are interested in making your own try downloading -FrootyLoops- its a cool music program that lets you make music yourself. It takes a little getting used to, but you could probably get the hang of it.
You can get free apps, free backgrounds, free music, and other cool things.
Jailbreaking is a process that allows iPad, iPhone and iPod Touch users to homebrew applications on their devices by unlocking the operating system and allowing the user root access. Once jailbroken, iPhone users are able to download many extensions and themes previously unavailable through the App Store via unofficial installers such as Cydia. A jailbroken iPad, iPhone or iPod Touch is still able to use the App Store and iTunes.
When you go to the iPod Touch, go to the App Store (after you're connected to Wi-Fi router) and choose categories. Then, go to the Utilities section. That section shows no games, just useful apps.
One of the most popular apps in the App Store currently is Angry Birds. It is a paid app.
