I was running FW2.0 since the release of the 3G. I managed to get 3days out of it with 6hrs usage in them 3 days. I jailbroke - for the only reason of me being able to change the New Mail alert sound and an SMS tone using SSH. I am pretty certain that the battery is not lasting as long as it was pre-jailbreak. People are saying SSH is to blame, but others say SSH terminates when not in use? I am going to try uninstalling SSH tonight - and doing a full charge to see how it goes. I would hate to lose the jailbreak as there are going to be some good useful apps coming (like Taskbar notifier hopefully). Anyone else having battery + jailbreak 2.0 related incidents?
