My phone doesn't recognize .jad, only .jar

I'm just wondering, because almost every other game and application is in .jar or has the option of either .jar or .jad. My phone doesn't use .jad, only .jar, and rumkin file uploader doesn't even attempt to send a .jad. Why isn't there a .jar version of this program? I'd really like to use it.

The JAR alone won't work since security won't be recognized (the JAD contains the digital signature), games often don't need security. Without the JAD the phone would however prompt you for every file access in MajiPlayer which would become very annoying very fast.

Jad's work on all phones via the web browser for the device or through special menus, I haven't run into a phone that doesn't support JAD (just click the jad link at http://majimob.com/mob/ ).

If you insist notice that every jad file is just a text file that points at the JAR file.
