Ok, caved a little, bought an official bumper for the iPhone (this is a slippery little bugger and I didn't feel safe holding it anywhere but on my bed, yes, I've slept with it, and I'm gunna call it back 🙂)
Secondly, I got a screen protector from CPW, which is one by Casemate and boy is it poor quality. Full of finger marks (more than the actual glass screen) and its not a great piece of "protective," film either. Very disappointed.
I'll hold out with it until it needs changing, but I cannot believe I spent £10 for 3 of these things.
