Hi there, I have a WPA2 network at home. I can successfully connect to it and use all web applications. The problem is that this only lasts a while. If I leave my iPhone for a while and try to use an app like 'Weather', it just sits there 'Updating...' indefinitely. Mail does the same with loading new mail. Safari just sits with a blanks screen and the spinning loader keeps going. No internet apps connect, even though the wifi signal strength is at full at the top of the screen. To get myself back online, I have to go into Settings and turn the wifi off and on again, then it works for a while again, but then stops seemingly spontaneously a bit later. I don't have any wifi problems like this with my MacBook. Has anyone else experienced this? I'm running 2.1 Thank you.
