AT&T says that the 4s goes into sleep mode and drops the WIFI connection. And any updates are done over the cellular network. Why the phone connects via 3G when it has a WiFi conn. available ? they have no answer.
Simple... it's not specific to the 4S. This is the way iOS is designed to work by Apple. It has been this way since the original iPhone was released in 2007.
