BlackBerry 8820 to hit AT&T for $299, 8800 to see quick exit?

We can't be sure until folks are actually leaving AT&T retail locations with 8820s firmly in-hand, but Boy Genius Report's latest intel allegedly has the WiFi-equipped BlackBerry on shelves as soon as next week. Of course, another tipster has it pegged for August -- we suspect no one really knows for sure -- but either way, it looks like it'll retail for a believable $299 on contract and the 8800 will be phased out very quickly to make room for the new unit. Not surprisingly, sales folk are apparently being asked to downplay the 8820's WiFi capabilities unless specifically asked -- it's a feature AT&T generally despises, after all.
