No offense taken.  I think it should be pretty clear that by "jailbreaking" I'm also referring to installing and using non-App store apps (what's the point otherwise?). I'm particularly concerned with the affect of running many apps that are using undocumented/unsanctioned apis (such as with the app that updates the weather icon). iOS has a bunch of restrictions to prevent apps from astonishingly degrading performance of the system (e.g. the API discourages or prevents apps from running invisibly in the background)
