Does apple fix jailbroken ipod touch?

No. Jailbreaking an iPod Touch voids your warranty. If you send them the device anyway Apple will be able to detect that you have jailbroken your device and refuse to repair it.

Wrong, jailbreaking an ipod touch became legal a long time ago... and with my research i can prove that if apple refuses to fix it, you can sue them and you will most likely win.
sooo yeah that doesnt ruin ur warrenty
