I got this for for development and testing (it's great) and would like to be using it as my personal phone. My problem is that after joining the Developers preview - mobile data no longer works, at all. Typical solutions of soft / hard rest, turning on and
off radios etc.. nothing appears to work. Phone calls and txt are fine, on wifi works great, but there is no cellular data at all on the latest update. (this really sucks, and shouldn't happen even on a development device). Any pointers, or do I just wait
for more updates and hope that it comes back to life?
Also, there is no Canadian English Language for Cortana - you still have to set the language and region to US for it to work. Is this also due to the preview for developers? Wish I hadn't opted into this now :(
