fuck no!!!! stay home... here is how to fix it.. plug ur iphone to the computer and make sure u hace a FUNCTIONING USB CABLE THAT WORKS... that u should get that lil sound in ur computer... (tee-reee) then hold both the power and home butten for exactly 10 seconds. then let go of the home button and keep holding the power button for 2-3 more seconds. u should be up and running. do not panic in case it does not work. last thing u want is to loose ur jailbreak on a 3gs..
