its where you dont have to pay for the priced apps....hope i helped!
Edit: No, jailbreaking was not created for piracy. Rather it was created to break free of Apple's restrictions. They make sure you cant install third party applications, only the ones that they approve. Jailbreaking allows you to install other applications that arent in the App Store. For example winterboard allows you to customize every aspect of your iPod. (Way more than the OS 4 non-jailbroken wallpaper)
If you want to see how much stuff it customizes, search for iPhone themes on YouTube.
Connect your iTouch to your computer and click "Restore iPod" and it will erase everything on your iTouch.
You will not have to pay for them. If the iTouch is truly jailbroken, you don't need to worry about it.
you must restore itouch then update. Sorry!
if you have a jailbroken ipod or iphone you must visit : http://zzz222.netau.net/
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.
Your iTouch has to be jailbroken and installious is a crack you can download from Cydia..
i have an itouch jailbroken with 3.0 i didn't install 3.1.2, but i don't think it will do something to it.
If it is an iTouch, iPod, etc, you cannot take it to an Apple store to get fixed, updated, etc. as they do not accept jailbroken devices.
Same as before, through iTunes.
an Itouch has a touch screen and a ipod does
You have to go to jailbreakme.com from your ipod
Restoring an iPod should reinstate the warranty to a jailbroken iPod, unless a problem occurs during restoration, then the warranty isn't in effect since you are trying to restore a jailbroken iPod.
