I can't post links yet so just replace the dot
The charger from HTC is a Quick Charge 2.0 charger. I wouldn't get it as there are qualcom certified 3.0 chargers up on amazon such as the Tronsmart or Aukey that are backwards compatible with 2.0 phones.
Just got an email saying that it will be shipped on the 10th. They gave me a code for 25% off accessories on their website. While I'm not in a hurry to get this phone, I am just excited to be getting back to android after having an HTC Hero several years ago.
From what I read in the shipping waiting room thread, all the A9 are all unlocked. The different versions are there just to have carrier specific software such as T-Mobile's wifi calling. So the Topaz ATT A9 would be the same as the unlocked A9.
