Can you feel the iOS 4.2 anticipation building ? After all, it's not every day your tablet computer gets upgraded to multitasking. Apple just seeded a new gold master of iOS 4.2 to developers (build 8C134b, as opposed to 8C134), which deals with the WiFi issue that apparently delayed the launch . As long as this build is free of any more killer bugs, that new copy of iOS should make its way to proletariat hardware soon -- though obviously this week looks like a no-go.
