Picture the scene. I'm on my iPhone, playing Airplanes Part II in the background while checking the App Store for updates. The phone, appropriately enough, is in airplane mode, but the WiFi's on. Suddenly, my music just stops. Surprised by this, I double click my home button. Nothing happens. I press it once. Nothing happens. I hold down the power button. Nothing happens. I slide my finger along the screen, however, and it responds just fine. I then notice that my WiFi connection's died. So I hold both buttons down and do a cold reset, and so far (touch wood) it's working fine. Has anyone else had a bug like this?
