Mobile Ready feature
If you wish to have a mobile version of you site there's a good point to use JoomlArt T3 Framework v.2 for developing your site as the framework already has built-in Mobile Ready Feature. In other words if you try to open you site in your iPhone or any Android device you'll see a mobile version of your site and the one thing to get it ready is to make changes in pre-installed JA T3 v2 templates. First you have to install JA T3 Framework v.2 on your Joomla 2.5.x based site.
Download the framework, install one and don't forget to enable it in Joomla Plugins menu.
Download free Joomla Art template JA Purity II template for Joomla 2.5.
Open Template manager and set JA Purity as default template:
Then click ja_purity_ii - Default link and click Profiles tab on the right side and then scroll down. Select iPhone for Android Layout in a dropdown list, save it.
Take your mobile device(iPhone, Android) and open your site in a browser:
Congratulations! You have a mobile Joomla site! :)
