This question already has an answer here:
I have a Nokia Lumia 630 Dual-Sim with Developer Preview, i have no more updates and i still have Lumia cyan. Am i wrong to assume that i can test denim with this phone?
"Will it run on my... Yes! Lumia 520, Lumia 525, Lumia 620, Lumia 1520, HTC 8X, Samsung ATIV whatever...you can 'Preview' 8.1 on all of these phones and get all the same features, even Cortana. Cortana is only available in the US? Change your region or just use the default Bing search like now." http://www.windowscentral.com/how-sign-windows-phone-81-preview-developers
