Am I jailbreaking wrong? I restore the 4.0 firmware, then set my ipod up & jailbreak with redsn0w 0.9.5b5-4. I uncheck multi tasking & battery percent and check install cydia, custom boot & recovery logo and enable use of background on homescreen. Then i jailbreak & download everything i had in cydia on 3.1.3 that will work on 4.0. But it dies so quick and it's frustrating not having a lot of the functionality i had on 3.1.3. Is there a way to downgrade back down or am i doing something wrong with the jailbreak?
