I realised that my personal ethics concerning mobile phones were interfering with business...
... so I went out, bit the bullet and bought an iPhone 4S, plus fabric-covered argyle case. Nobody can ever complain now that I'm late to interview someone because I'm stuck waiting for a train... they'll be getting a phone call.
Edit: Oh, and smashed myself in for a haircut. I refuse to attend my best friend's baptism with hair like a hayrick.
