iPhoneAlley notes that iFuntastic 2.0 has been released.
iFuntastic is an Intel Mac Version two brings improvements to the custom ringtone feature, allowing you to add ringtones from anywhere you choose. The ability to change carrier logos has also been added, as well as the ability to change the icon display order on the home screen. Just like version one, iFuntastic v2 is super easy to use. There's been a lot of work done to make the instructions clearer, when they're needed.
Requires an Intel Mac. Download link available (version 2.1.0). Due to the nature of the application, you should use it at your own risk as these hacks are not supported by Apple.
