We've already seen Microsoft try to buy the love of carrier retail employees, but it would seem that Nokia is the one coughing up cash this time around. According to WPCentral, Nokia is paying up to $25 million to get AT&T retail staff to use a Nokia Lumia 900 as a "Company Use" device. This would basically mean that when you walk into an AT&T store, where you'd normally see guys in blue shirts tapping away at an iPhone or Android device, you'll instead see guys in blue shirts holding colorful Nokia Lumia 900s.
