Well I installed the WordPress Mobile Edition plugin. I had a quick look on my iPhone and it rendered quite well. The only thing I dislike about it is that it uses the Carrington theme engine instead of K2 which the blog is based off.
I also added the Wordbook plugin which also adds any posts that I create on here to also display on my Facebook Profile. This seems to be quite a good way for both my blog and Facebook to come together.
It should render fine on most mobile devices, if you do have any issues with it please leave me a comment!
