I'm confused at what the question is?!
Do you mean O2 the mobile network in the UK? Windows Mobile OS on PDA/Smartphones!
I get the feeling that you are actually talking about the Apple iPhone or Windows Mobile as the iPhone is out on O2 in the UK.
You can't really compare a mobile network and a OS for mobile phones!
Though talking of that, I Think I'll create a thread on that, wanna know what people think about the iPhone!
