This is mainly for the UK users but may be applicable to others as well. Two days ago I noticed something different about my home screen. The name "O2" (the UK's iPhone network] suddenly appeared in the middle of my screen, right underneath the time. My wives iPhone hasn't done this though? When I put both our phones next to each other you can see that all my apps have moved down ever so slightly and have become slightly more squashed together. What does it mean and why has it happened? I'm not particularly bothered, just curious!
