Sideloading Good for Enterprise?

Hey @all,

I want to purchase a smartphone with a hardware keyboard + touchscreen.
I choose (you don't have a real choice) Blackberry Q10 or Classic.

It's neccessary to load the app Good for Enterprise to access to my business e-mails (my Company only provides Microsoft phones w/o hardware keyboard)

But there's no native app for BB10, and no app in Amazon app store.

Maybe someone of you tried it and can clarify if it actual works.

Thanks

My company's I.T. department is using the GOOD apps for employees owning Android devices from different makers to access their corporate emails.
This application is not easily available thru any channels unless your I.T. or H.R. department had purchased the user rights and you get them to install it into your phone. So far i had only seen the application used on different Android makes, non of the employee have this sideload into their BBOS10 device.
