Okay so basically I am an "add a line" on my friends cell phone account. I haven't bought an app in two years that I've been the add a line to his account 
I was looking to purchase a few apps that I have use for at this time. The only problem is when I try to buy them, it says purchase will be billed to the main account holder. Which would be my friends mother. I dont really want to have to worry about informing them all the time when I buy an app, etc. Is there anyway I can seperate myself from that, and add my own credit card that the app purchases would be billed too?
