This thread describes how to set a custom "carrier" logo for the iPod, and whilst looking at this I noticed that there are other carrier logos in the Springboard App, but not one for O2. Now, assuming this app is the same for the iPhone and iPod touch (and there are a lot of things common to both), there will have to be an update before the UK launch of the iPhone, or else the UK iPhones will have a different version (unlikely). So, the result of this is that I think there's a pretty good chance of an update to both the iPod touch and iPhone firmware in the next couple of weeks: I wonder what Apple will include to try and get everyone to lock their iPods back down and apply it?
