There are many ways to implement mobile version of your website but easiest and probably cleanest one is to use mobile subdomain.
Once you have your mobile website you want to implement an automated test suite to be able to regression test the functionality after every release. You also want the test suite to be easy to configure and run it against test environment. In perfect world you want the test suite to run as part of the continous integration setup. Jmeter allows for all of that and is free. As a huge fan of jmeter i recommend you download it and play around with it as soon as possible.
In this article I describe how to create a test suite for mobile website redirects, you can also download my jmeter test plan and customise it to test your own websites.
I know it is not really anything special in our times to have mobile skin of your blog or website but it is still a nice thing to have. I am sure that there are tons of ready to use plugins for the software that i am using but i wanted to play around a bit myself and learn some new library. My blog is my little sandbox any way so i prefer to learn on it and make mistakes here than in real work.
