Well, a question and a couple of suggestions:
1. Can you post that picture with wifi turned off?
2. Try usernames vertigo and mobileweb. Try also wap.o2.co.uk, usernames o2wap or mobileweb
3. Try asking O2 customer services or the local O2 store for a replacement contract SIM card with 3G and life will get a whole lot better. I believe they'll send you one free.
