Interestingly enough, I stopped by my local Verzon (Corp Store) to check out the flip case for the G2 and the Sales Rep said, "they don't carry accessories until the phone is released" and that the "G2 is available for pre-order only." I asked to speak to a Manager who said the same thing only added a condescending "I have been the Mgr here for years and know my inventory."
I thoroughly enjoyed whipping out my G2 and dropping a "well I guess I'm from the future?!" They spent the next 30 minutes finding the phone in their inventory and asking each other about specs, selling features, etc.
Bottom line: Verizon doesn't care about the G2. However, they're all trained up on the motox, S4 and upcoming 5S
