I'd like to open my developer activity to windows phones, Windows Phone 7 and 8. I'd like to own a test device. The Nokia Lumia 520 appears to be really affordable, but the only OS spec available online is "Windows Phone OS".
Could someone tell me which version of Windows it is? WP7, WP8, Other?
Which cheap Windows Phone so you use to debug Windows Phone apps?
Lumia 520 ships with Windows 8.
It is a successor to Lumia 510 which came with Windows 7.
It's a good device to test on if you want to check how the app will run on lowest commonly used hardware. However it lacks memory compared to higher end devices.
