Everytime I try to download an app, free or paid, it always brings me to a "sign in to continue" box, when I sign in, it brings me to my iTunes account info, everything seems right, so what should I do?!
This is getting very frustrating. (it happens when I try to download music to)
It kinda sounds like Apple wants you to check or change some data on your account. When you signed up for your iTunes account, did you put a credit card on file? If so, could it be expired, or full? Did you use PayPal? Is there money in that account?
There is obviously something wrong with the account. You should log into your iTunes account on a computer and check the settings to make sure everything is up to date and correct, unless you already are.
When I purchase an app or music, I just enter my password on the phone and it downloads. There is no checking of information.
Please don't take this as trying to pry into your monetary standing, but these are all things that could be a possible problem.
