Hi I'm brand new to installing games and apps on my phone and I recently downloaded some games in .jar format for my phone, but I couldn't get them to work. I tried putting them on my phone, but it doesn't let me open them. I also tried opening them on my computer while my phone was plugged in, but I got a mainframe error message. I have an Lg Sentio is there anyway I can install these games or is there a better way to get free games on the phone? Thanks in advance.
