This is interesting. I looked through the Verizon G3 manual and it didn't mention wireless charging at all in the section where it talks about charging. However, at the end in the Safety section it mentioned:
"Instructions for Wireless Charger
Be sure to use a wireless charger that is genuine or compatibility-
certified (by WPC Qi standards).
(Wireless charger is sold separately.)"
Here it didn't say a separate battery cover is needed. If the cover is included, however, why didn't VZW market the hell out of it?
Anyway, I'll keep my expectation low and hope for a nice surprise.
