can someone possibly help me? I have tried numerous times to download games noth the jar and the jad files of games to put onto my Samsung Solstice SGH-A887 cellphone and keeps telling me "wrong file type - file not supported" It's driving me batty!

I have searched both high and low on the internet and no way I can find out "how" to do this so I can play them on my phone I don't have internet on my phone plan, and I don't have a data link cable....BUT do have a 4gb micro sdhc card, that I have heard you can save it to the card and place the card in your phone and should be able to work, but no luck here so far on my end

Any and all help greatly appreciated.
