I am pretty sure you are out of luck. Apple patched the browser exploit awhile ago. If it is an option, use a friends computer.

Jailbreakme was the only jailbreak i know of that works without a computer. If its not working i dont even need to ask what firmware your on. You need a computer to jailbreak.
