Best content managment script for a mobile content website

[khuldun]

Hey... i am looking to setup a mobile content website... pretty much on the lines of mobango.com / zedge.net but im having trouble finding some decent script or even some script resembling them. I do not want to make a carbon copy of the above sites but i need some script that can cater to the requirements of such a website. I have the design all made up and its pretty much adaptable to any script... any suggestions would be really appreciated.
