...notices? I got the iPhone with the prepay plan, but every time I send or receive a test message, use the browser, or check email I get a message about how many minutes I have left that I have to dismiss. And if it checks email every few minutes, when I come back I have to dismiss several notices. So annoying!Anyone know how to turn this notification off? I've checked all the settings screens and haven't found anything. Thanks for serious responses.
