I am constantly trying to upload a jar file to my Samsung Impression phone. But I am not able to do so. I always keep running into brick walls trying to do this and for some reason which I don’t know, instructions are not working for me. I have a USB cable and PC studio program to do this, but the file is not showing up when I try to upload it. How to download jar file to Samsung Impression phone? I would really appreciate if someone can help me regarding this. Thanks.
