Okay, So I just jailbroke my iPod touch 2g. I open up cydia and I type in tetris, and I get nothing. I really want some tetris, so I google it and find iphonexe.com. It seems pretty cool and it seems to have exactly what I want. I click download and I get this tetris.app. I don't know what do do with it, and I don't know how to add it, and I don't know what to do. HOW THE HECK CAN I GET ME SOME TETRIS????
