Ive noticed maybe 4 or 5 times over the last week, it seems my wireless signal just seems to be randomly disabled or switched to airplane mode. first time it happened, I was at work and got a "service unvailable" message when I tried to use the browser. I figured either I had a bad signal even though I had 2-3 bars showing or their service was down or something. The problem continued at home and when I checked it out, it appeared 4g had been disable and it appears 3 g was disabled as well. A couple of days ago the same thing happened and when I checked the wireless settings, it was in airplane mode. I was using launcher pro and thought that may be causing some weird problem but I don't think so. The only thing I can think of is maybe some random app is causing it or it's a glitch in the system. Has anyone else ever seen this?
