German airline Lufthansa is offering a free flight to Germany for Gray Powell, the Apple engineer who accidentally left a prototype iPhone behind at a German-themed bar in California. Specifically Powell is being offered a business-class flight to Munich, where Lufthansa has just opened a beer lounge. "I recently read in the news that you lost a very special phone at a German beer bar in California," reads a letter from the airline's Americas marketing director, Nicola Lange.
