<p>Well, i got the samsung gravity T a couple days ago but, i’m kinda bored with my apps and i don’t feel like paying for any apps so, i bout a micro SD chip and an SD adapter. I popped the thing in my computer and i downloaded a couple apps from GetJar.com.</p>
<p>So, the file format is called a .jar file. It looked pretty weird to me but, i draged and dropped the file into my micoSD card and popped the thing in my phone but, when i tried to launch the app on my phone, it wouldn’t work. Anyone have any idea what i should do?</p>
