Looking for user with WP8.1 Cyan device, not with GDR1 or 2, to test something

[N3croman]

Hi,
I'm looking for a user with Windows Phone 8.1 device without installed Update 1/GDR 1, basically with Lumia Cyan only, to test one website for me. It's a really quick test, 5 minutes max.
​We've received feedback that one of our apps is not working on those devices and unfortunately we have no WP8.1 Cyan device for testing.
Thanks!
