OK I've had my iPhone 3GS for about 3 months now and just over the past month or so i always get the stupid "Network Lost" (Cellular) notification right in the middle of the screen. Is there any way to turn this off? Where my house is the signal is a bit hit and miss so it means it comes up every 2 mins which is especially annoying when im in the middle of something. Is there any way of turning this notification off? I've already turned the notifications option off on the setting but that only works for the applications
