I don't get why people are making such a huge fuss of this.
How many days consecutively have we had perfect O2 coverage/reception (location variables excluded)? I can't remember the last time it went down, and it's not like they're just sitting around scratching their balls wondering what to do. I bet the engineers are working some serious overtime to get it sorted, and their customer service have been pretty open and up front about the problem. Sure, for some it's an inconvenience, but it's not the end of the world. You've probably lost more days of O2 service in the last 10 years because you've run out of battery than over this minor issue.
And yes, mine too is no longer working this morning. Nice quiet day for me!
