Well, my 4S arrived yesterday, and I have to say, I'm underwhelmed. Okay it's faster than my 4, but the most interesting feature (siri) has very little use in the UK. It does the basics, clock, mail etc. But has no map function as yet. If you stand the 2 phones together you wouldn't know which was which. My first Apple disappointment for a long time. I guess we will just have to wait for added function as time goes by.
