i don't exactly understand what jailbreaking is.
can someone send me a page that explains it or explain it themselves
dingAlso, @OP: while jailbreaking your device does void the device's warranty, if you encounter a problem with the device, just restore its original OS before bringing it in to the Apple store. A friend of mine had an iPod touch that, by the fault of him being stupid and installing certain apps and mods that are incompatible with each other, stopped functioning properly. He simply restored the original OS. Restoring and rejailbreaking is usually enough to fix any big problem you might have, but if restoring still doesn't fix a problem, just bring it into the Apple store with the original OS installed. They won't be able to tell you ever jailbroke in the first place.
