Hardware and Software Compatibility with BLE Shield v2.x


I am curious about the compatibility with BLE Shield v2.x.

What OS for an Android/iphone/ipad does it support? Through iOS 11 or equivilent?

What is the compatibility with hardware? Phone and Tablet. Product detail page (http://redbearlab.com/bleshield/) only says through iPhone 5 and iOS 8… thats a long ways ago. Is that still true?

Can you please provide a workaround?
