Remove Apple Device <2011 Support?

Unity Engine

I’m currently using Unity 4.6.3 - I noticed no matter what I do devices that where released before March 2011 (iPad original and iPhone 4, iPod touch)(http://iossupportmatrix.com) always have slow frame rate and issues, I know these are old devices and no one can bother supporting them fully anymore unless games are 2D etc.

So what would be the best way to restrict customers with these devices from downloading my game. I firstly thought it be best by iOS version but this is no good as I know iPhone 4 has firmware 7.1.2 and some users on the iPad 2/Iphone 4s could have the same version.

Any advice would be most useful?

Thank you

Restricting to opengl 2.0 or ios8 usually works pretty well for me (especially ios8 as that restricts to 4s and above on phones)
