I have older iPhone and cannont load iOS 8.0. Is an older version of square reader available? Where can it be found?

Hi there!
 

Unfortunately we no longer provide the old version of our Square Readers. 

I recommend using using the most up to date version of our app since it includes all of the latest features as well as any fixes that we've released.
