I need help fixing Apple billing info?

[Artentreri]

So, I'm trying to update my apps, then it tells me my billing info is invalid. Now, I've never even put a credit card number on this thing, just gift cards. Anybody have any clue how to fix this? It sucks so bad, infinity blade 2 just got a new content update!

Log into your itunes account and email them or call them. They're pretty friendly. Or they were like years ago.

Sounds like maybe you're out of money or they have a new TOS you gotta accept.
