...to put games on it with the card? I've tried putting the .jar files in almost every folder but they still won't show up. I'm using US Cellular, not Verizon, so there aren't as many restrictions. Can somebody please help me?

Yes you can. You can buy them from your cellular provider or various other websites. Just make sure that you save the gave to your memory card and not your phone. So that way if your phone ever becomes defective (like my V3 did 3 times in 2 months) you won't lose all of you data like I did.
