I really need help
they open for 1 second then close

I've restarted
what's jailbroken

its every app. whats firmware?

Firmware is basically what operating system that your ipod touch runs on, people make it sometimes, then people download it, and that's jailbreaking, which is strictly against apples rules. Hold down the top button and the circle button at the same time until it turns off, then plug it into your computer and restore it.
