It usually happens when I'm using my HSDPA+ connection. This usually happens about 4 or 5 times a day now. A 'solution' is to do a battery pull, but that isn't convenient when you need to call someone immediately and your £300 is acting like a brick.
I'm on 3UK, here's a screenie of my info.
Also, my ERI Version is coming up as Unknown and so it my Mobile Number
I'm not rooted either
