The Icon never had DTTW. So it never got removed.
The Icon had Denim before anything on AT&T.
AT&T neutered their 1520, still hasn't updated their 830 to support the latest Lumia camera features iirc.
How does it make sense to narrow your customer base that you're trying to grow by taking the extra effort to cut some of them out?
Look my post wasn't a my carrier is better than your carrier argument, it was simply showing the Verizon precedent for not caring about WP users. Every Lumia 930 in the world (as far as I know) has double tap to wake, except the Icon, Verizon's special order 930. Let's not quibble over semantics of it being a different phone than the 930, etc.
Yes AT&T made a dumb call on the 1520, but they at least offered the 1520. And they didn't double-down on the PMA mistake, they rectified it with the 830 by leaving everything in tact (in fact they added PMA on top of QI) and even offered a 32GB version of the 1520 later. Yes the 830 doesn't have official denim yet, but there are alternate ways to get this (just updated my wife;s) and you could always buy an unlocked 830 if you chose. See on AT&T's network we have choice, I myself imported a 930 to use. On Verizon, you get...no...choice. That's the difference, so Verizon should be working harder to provide Verizon users with as much choice as possible device-wise.
Let's talk about narrowing your customer base. Verizon right now has 23 android devices available on their website, many of which we all know are ****. And three windows phones, two which are basically new releases but are budget devices. The flagship device is not the one preferred by most of it's windows phone customers (the Icon), and it's over a year old. Verizon has total control over whether or not they want to play ball with a part of their userbase. They don't care about WP, it has nothing to do with MS at all. You say MS went through some extra effort to cut out Verizon, well I have yet to see any actual proof of this. It's easy to just say MS disabled the bands to be petty, but what we have no proof of is whether or not they were forced to do so because Verizon wouldn't certify the phones due to their demands, etc. Remember how long it took the iPhone to get to Verizon? That was all Verizon, not Apple. So until we have actual definitive proof, let's just make the safe assumption that Verizon **** on us again. It's kind of their thing.
