My Lumia 830 just updated to denim os .341. This is the requirements to go to 10. Not sure if this was done by att or by me using the developer preview. Any how, I'm updated.
If you're on the Developer Preview then that must be it. Unfortunate, as the thing I want most in the world right now is for AT&T to release full Denim to my lovely Lumia 830.
Well turning the Developer Preview off won't delete updates, it'll just stop them from coming in.
If I don't get the Windows 10 Mobile update, I'll just join the Windows Insider Preview program. No big deal as I already have devices on it.
