iOs 4 wake on wireless

[achtungbaby]

Whenever I press the home button to open my iPhone I notice it will still say 3G and within a few seconds change to the wifi icon. Am I mistaken that wifi should stay running even when the phone is closed?

It uses 3G while in standby, unless you keep it plugged in or are running an app.

This is not correct in iOS 4.

The icon is merely a quirk of the OS.

It does this even when plugged in at home and I'm always on wifi at home.

Yes, you're correct. Forgot about persistent wifi which is a feature of iOS 4.
