Here is another method of rooting 2.0.2.A.0.24, it was posted here. This method seems simplest of them all. But if you can not get this to work do not worry there is 2 other methods as well. For this all you have to do is download the file then execute the rootme.bat file on your computer. Remember that you need to have your phone connect via USB with USB debugging enabled.
