Jailbreaking doesn't speed up anything. You can install tweaks that make the effects go faster but the system won't be sped up. The iPhone 4 will be slow on new versions of iOS because it's outdated hardware, there's no way around that.

Try restoring your phone. Maybe youve got a lagging process running thats slowing everything down. If it doesnt work, then go ahead and jailbreak. What do you have to lose?
