Review to sign in

I've just resolved this by myself.

It's so frustrating because I've tried everything first - resetting Ipad, creating a different account, making sure I have Billing info (you don't need it, btw) and none of these worked!

Eventually, I realized I'm getting a blank page after I press "Review" because the page just fails to load on the Appstore or on the Itunes. Thus, I did the same thing, but on a different device.

How I fixed this:

1. I downloaded the iTunes app on my laptop. (Basically, you need to load that page with a different device.)
2. I signed in and I immediately got that same message prompt.
3. 
4. I pressed review and then I got that page that I WAS LOOKING FOR A LONG TIME YEAAAAASSSS!!! (seriously, that's how I reacted, jesus.)
5. 
6. Go through the whole thing, next page is the billing. You don't need to put anything. I left Payment Method blank and it was OK.
7. 
8. Then you're done!
9. 
10. I went back to my iPad - restarted the appstore to be sure, to be sure.
11. and lo and behold, I can download apps. YESSSSSSSSSSSSSSSS

I hope this helps!

Do you have access to another WiFi network where you can try? That has worked for several people.
