Things you need:
2 apple ids
any cc with at least $1
1) Add the cc to id you intend to burn
2) get a list of apps you want.
3) go to the app you want and send it as a gift to your other apple id
(keep doing this for other apps)
*always send it as a gift because apple will limit you account after so you wont get app updates
4) use the code you recieved in the appstore and enjoy...
(make sure you get apps worth more than a dollar so that apple wont charge your card)
