I work in a place where there is zero AT&T reception, but WiFi coverage in 100% of the area. I just read that iOS4 will allow WiFi to stay connected even when the device is in standby,, IS THIS TRUE?! And if so, could I just get a skype landline number, stay connected to WiFi, and use my iPhone 4 at work through Skype?! (please say "yes"!) EDIT: Alright.... iOS4 is out... any answer to this question?
