[hub1]

My Iphone conncects to wifi fine, but it doesnt remember the password very long, keep having to reenter it every now and then, have tried resetting network settings but that hasnt made a difference

I'm having the same problem. My Iphone 3g V2.0 firmware won't remember wi fi passwords. I have to keep re-entering them.
Anyone have any fixes for this problem? I assume the phone is supposed to remember the wi fi passwords?
