So we all know that the iPad 4 won't get any of the multitasking features at all, but it seems that content blocker is not available either. I've checked two ad-blocker apps already and both are "not available" on my iPad (install fine on my iPhone 6). Can anyone confirm this? This sucks if it is true. The 4 is still running perfectly fine. I was going to get the air 3 but they didn't announce one last week so I'm planning on using it for another year at least.
