a couple strange behaviors with the phone app in iphone... when i am dialing out, and i recieve a call simultaniously, i cannot switch to the other call. i am forced to hang up and reconnect manually... anyone else? once, i recieved a call while switching from silent to ringer... and the phone just kept on vibrating while i was trying to talk to the person. i had to hang up and try again.... anyone else experience these problems? r.
