The cleaning side I do once a week, maybe. Depends on how much I've used it. Cleaning the application cache speeds things up no end, like facebook and the 500px / ISO500 apps that I use.
Launch Daemon side of things;
Safe daemons; off
log, dump and crash; off
developer; off
ota update; off
addressbook; i've left on
assistive touch; off
airprint; off
custom vibration; on
spotlight; on - not sure whether to turn off though, undecided
chinese WLAN; off
admin lite; off

voice control; off

game center; off
passbook; off

tethering; off
twitter; on
data partition; on

iPhone 4 - Do what you please though. I've turned off what I know I don't use. The partition and migrator ones I've just left on. Can't see them using any RAM during normal use surely so I've left it on. Unless someone can correct me.
