there is a simple way to get paid apps LEGALLY....
just goto android market, pay it and click install..
now check in /private/ folder in your sdcard or memory, your apps original copy is there, just copy it to another folder,
then goto android market of that paid apps page, you will see, it show as "installed" now click unistall button there.....YES you will get your amount back in your account...
That's all
Enjoy all paid apps, 100% legal though...
