Hey. I downloaded an app for my Pantech Pursuit using my laptop. After decompressing the downloaded files, they were all .jar and .tar and .tar.tar files. After moving them to a micro sd and trying to open them on my phone, I keep getting an error message saying that the format is not supported. What on earth am I to do? I have been obsessing over this for days and there seems to be no useful information on the web about this. Please help me. I am going mad.
