Newbie here... I have the iPad3 & my wife just got her iPad2, we share the same Apple ID to be able to share the Apps that we both might choose & we have our separate e-mail accounts set up on our individual iPads. If I purchase an App for "whatever cost" (not free), it goes on my credit card... Our question is can hers be set up so if she purchases a "whatever cost" App, can it be charged to her card or does it have to be on my card since we share the same Apple ID? So far, we've both only downloaded free apps with me only purchasing a "couple" apps & she asked me last night this question & I had no idea... Anyone help? Thanks!
