    Just curious --when my 3g and 3gs were asleep but wifi enabled when I would press the home key to use phone it would display the 3g--but connect to wifi within 2-3 seconds

    It seems with the iphone 4 when i go to use phone the wifi status is already connected making it seem that the connection is constantly on and was never shut while asleep.

    Only thing is I really haven't noticed decreased battery life so maybe Ios4 just keeps the wifi bars there to let you know its still turned on.


    What are your thoughts?

    I think this change was primarily made so that iPods could be used as reliable Facetime devices that could receive calls at any time of day.

    It has many other benefits (and spread to other devices when they decided to make it an OS change, not a device change), but I think that was where it started from.
