MobiOpt is a mobile detection and optional redirection script. If a mobile device is detected it will pop up a modal box asking if the user wants to be redirected to a mobile version of the website or webpage.
Version 2.0 is a complete rewrite – with a 55% code reduction! It no longer uses PHP or 3rd party jQuery plugins! It’s lighter, faster, easier to customize, and easier to install!
There is no real need to upgrade from 1.0 to 2.0 unless your concerned about code size.
