hello, I have the LG Muziq (lx570) and I want to install a stopwatch program so I downloaded the jad file and jar file and have put them on the memory card for the phone but when i try to start the file it says "invalid file." I was searching the internet for how to install a java application but apparently everyone knows how to already except for me because i couldnt find one instruction guide on it. I would prefer to install it through USB to my computer and avoid paying data charges. Can anyone please help me out? I posted this on other forums like sprintusers.com and howardforums.com and got zero responses.
