What does the IcsService process do? Under running services, I see the IcsService or long name com.android.samsung.IcsService . What does that process do? I'm debating about removing it.

Note I have a AT&amp;T Samsung Captivate (Galaxy S)
ICS = Internet Connection Sharing.  I believe it's the service that lets a computer connect to the internet through your device over USB.  You can safely remove it if you don't use it.
