HTC One Developer Edition

One more question - you mention a T-Mobile update. I'm not sure that you or I will ever get that, as I've been told we don't get updates from T-Mobile, only direct from HTC. I wonder if anyone here has any thoughts on that?

We won't get them from T-Mobile, as we didn't buy the phone through T-Mobile.
We won't get them from Google, as they don't have the ability to work with Sense.
I think we get them direct from HTC, but I can't find anything to confirm that.

Maybe everyone thinks we got unlocked phones, so they don't need to send us updates???
 
My LTE issue is that 2 apps I know of (Twitter and Instagram) will not refresh while on LTE. They will refresh on Wifi, on HSPA, just not LTE. I can do other stuff on LTE like browse the web and use Spotify.

I actually flashed the newest radio onto my One DE and it made no difference in regards to my specific LTE problem. I will let you know if I see improvements otherwise, but so far it seems the same as it was before.

As far as the contact photo thing - sorry, I don't really have contact photos in my phone or on Google so I can't help you out. I think I have read some stuff about your specific problem and the way you are doing it is either the way people are working around it or at least one option for doing so.
 
I have the Dev Edition.

The updates should come from HTC, but they don't come as fast as you'd think. I got the phone at launch, and there is still no 4.2.2 update for the Dev Edition. Don't hold your breath for them.

I just converted the phone from the Dev Edition --> Google Play Edition. I'm no expert at this, but i followed the two guides below to make it happen. It involves changing your CID ("Carrier Identification") to match that of the GPE ("GOOGL01"), so then google will see it as a google device.

There is also a thread on XDA about how to get your phone completely back to stock: [GUIDE] Easily go back to 100% stock - xda-developers

I feel your pain re: the difficulty in following the guides. Threads on XDA tend to be very acronym-heavy and so long that it's impossible to find anything.
Check out the guides on htc-one.wonderhowtwo.com, including the one I linked to above. They are very simple and gave me a good idea of what is going on.
