So, I've got to say that my Windows Phone 8X by HTC is loving this WP8.1!! Everything is nice and smooth, I'm appreciating all of the new stuff that came along, but I'm using Listen, instead of Music. Camera works great still, no random resets, battery has been good, Wi-Fi and 4G are still great, have Extra Tiles showing with a kick @$$ background, Cortana loves me, Bluetooth sharing is the $H!T and its all on my 8X (actually all 3 of them)!!!!
And I don't even have the firmware from GDR3 yet, T-Mo....
I feel for you folks that are having issues, but....
My 8X is even more 'el chingón'!!!!
