If you are using HTC’s Radio application to listen to some stations and you’re tired of its Sense look (which I personally like), you now have the option to apply a skin to the program.
Download the CAB file and install it to your Device, followed by a Soft Reset. This contains the graphic files needed to skin the application and will overwrite the original ones but if you want to revert, just uninstall and Soft Reset.
Note: WVGA only!
