I like speed and dislike lag. My phone launches app in seconds now. When I jailbroke there was a noticeable difference. I didn't like that. The thing is though I still have the battery percentage on my iPhone 3G even though its not jailbroken anymore. My battery life didn't last long. I had SBsettings installed and BiteSMS. I liked SBsettings for the fact that I can access a pull down window to toggle brightness, location service etc, but I can live without it. I use Free Memory (Its not on the App Store anymore) to kill apps running in the background.
