One of the more hard to find accessories for the Nokia Lumia 1020 is the Wireless Charging Cover. You can pre-order them through Expansys or Amazon.com and there's no telling when (or if AT&T will carry the charging cover). However, there is a ray of hope out there. We aren't sure as to the when but the Microsoft Store is listing the charging cover and best we can tell it is ready to ship.
The Microsoft Store is only listing the black cover (comes in white and yellow as well) at a price of $39. Standard shipping is free and you'll have to pay local taxes.
The pricing is slightly higher than what Amazon.com ($26) or Expansys ($33) has the covers listed for. But if the covers are ready to ship, it is worth the extra few dollars for those missing wireless charging. It is one feature on the Lumia 920 I really miss.
You can find all the details on ordering the Nokia Wireless Charging Cover here at the Microsoft Store.
