Hello all. Long time macrumors reader, first time poster. I have a 16gb 3G on AT&T and I had a weird experience today. I was surfing the web with Safari and then all of a sudden the whole screen grayed out and a "Connecting" message popped up in the middle with the 'loading' spinning thing next to it. While this happened I couldn't do anything with at all. Touching it did nothing, neither did the home or power buttons. I decided against resetting it. After about 10 minutes it went back to normal. This is my 4th iPhone since Feb 2008 and the first time anything like this has ever happened. Anyone have any ideas what it might've been? Edit: I just found somewhere that this happens when the iPhone connects to a WiFi network. One problem. My WiFi was turned off, and even if it were on, I highly doubt the place I was at had a WiFi signal.
