Making your WordPress blog Mobile Friendly is an easy task.
All what you need to do is to install the wonderful Verve Mobile plugin.
You can install the plugin by:
1. Download the plugin from here.
2. Unzip and place the ‘verve-mobile-plugin’ folder in your ‘wp-content/plugins’ directory.
3. Click the ‘Activate’ link for Verve Mobile on your Plugins page (in the WordPress administration page).
After that you can configure the mobile theme, the number of posts to display per page, the social settings and more from the plugin administrative page as shown:
After doing this, the plugin detects automatically if the device accessing your blog is a mobile device to render the proper mobile interface.
I wish that this tip can be useful.
