There is absolutely no reason to jailbreak right now with Cydia yet to be updated. Everyone (99.9% of jailbreak users) should wait until Saurik updates Cydia installer and it gets packaged into an updated Pangu setup.
Again, there is no Cydia included with Pangu ios 8 jailbreak. (AKA its useless until updated)
