Hi i downloaded some games of one of those free game sites to my pc then transfered the 2 files, a .jar and .jad to my mSD card poped it in my phone and tried to run it but i get an error that the files arent supported, after searching a bit I have found posts about unlocking java ect and long codes you have to type in to enable support, is that the case here and if so does any one know the code for a m520?
