Can someone explain these processes?

[xavierpunkreno]

I'm trying to figure out what is killing so much RAM on my iPhone 4 when nothing is running apparently. I'm now averaging about 180 RAM with nothing open. It used to be over 300 at the least. Here's a list of running processes. If anyone can fill me in on what they all do that would be awesome. (I won't list the obvious ones like MobilePhone and MobileMail etc.)

ptpd
lsd
dataaccessd
imagent
apsd
notifyd
BTServer
accessoryd
awd_ice3
configd
fairplayd.N90
mDNSResponder
launchd
kernel_task

ptpd
lsd
dataaccessd daemon for assessing data?
imagent
apsd
notifyd daemon for notifications?
BTServer daemon for bluetooth
accessoryd daemon for accessories
awd_ice3
configd
fairplayd.N90
mDNSResponder Network daemon
launchd
kernel_task Kernel task is what it says

Most of those should be running except for a couple I'm not sure on.
