Well, a few weeks ago my sister and her husband were able to get a couple of Sprint Evo Shift's from a mall kiosk vendor. Got a really good deal since they got $250 back using Sprint's move a number to their network and get $125 per line in kickbacks.
Anyway, I believe the reason Sprint has not been stocking the shelves with both the Evo and Evo Shift is probably because of the the drama between Sprint and Clearwire about the 4G network. After all, how many Clearwire 4G handsets does Sprint want on their network when they may be planning to switch to the LTE technology. I have not read about any new 4G cities going live in a long time and we all are paying the $10 now whether or not we have access to the present 4G service. So, we get what we pay for from this mom and pop Sprint network because the other two carriers can monopolize U.S. wireless pricing plans and technology. After all, it was Sprint who has kept pushing the U.S. market as the two big U.S. carriers don't really have a completely usable 4G network in their house.
