If you are using Blogger (in draft), there’s a new feature called Mobile Templates. You can reach to this by going to Settings ►Email & Mobile ► Mobile Template (beta).
The worst part is, there is no automatic redirection to the mobile template when the user visits the blog from a browser like Opera Mini. I had to implement an additional workaround.
Clicking on Preview after activating this feature lets you view your mobile page. Copy the URL of the mobile template and set a URL Re-direct to the same for m.website.com or mobile.website.com or wap.website.com
The Mobile theme looks pretty cool. If you are using AdSense, the mobile version of the Ads flash at the top and bottom of the webpage.
