I had installed the "quick settings" app that was mentioned in another thread. When I tried to open it this morning to turn on the mobile network (I usually keep it off at home), a message popped up saying the application was not updated properly and it needed to be removed and reinstalled. I tried to go to settings>wireless controls to turn on the mobile network but that isn't working either. When I look at the button to turn on the mobile network in the settings, it says "standby to connect to mobile network", I click it, it goes away and says "connect to internet" but when I click it again it just tries and then stops after a minute or so. I removed the quick settings app and restarted the phone, but that didn't help. This happened once before and I just connected to WiFi and reinstalled the quick settings app, but now I'm somewhere where I don't have WiFi access. If it matters, I also have a shortcut button installed to turn the mobile network on and off, but that isn't doing anything either. Any suggestions?
