Hey guys, I am going to be going to London for 6 weeks for work in a few weeks. I know they use different types power outlets over there and just wanted to know if anyone can recommend some adapters I can use for my cell charger/ camera battery charger/etc and laptop charger.

I also wanted to know about pre-paid SIM's that I can throw in my unlocked phone. Any recommendations on some good deals and good carriers?

Any other things I should be concerned about?

Thanks in advance.
