ok so i flashed to 2.1 really liked it but couldn't get my paid lotto ticket app in the market the free version is there and another app i purchased is there but not this one so i went back to 1.5 rooted now is there anyway that i can save the app on either my sdcard or my comp. so i can just install it as i want to go back to 2.1 for some of the great features.
