You can say that the Mobile World Congress isn't one of Apple's territory; arguably more of an Android-centric affair this year. But despite the lack of appearance of the iPhone makers, the company was awarded the award "Best Mobile Device" for the iPhone 4.
According to the judges of the panel, the iPhone 4 has a "great screen, sharp design, fantastic materials, and phenomenal ecosystem for app developers. In a tight race, the iPhone 4 built on the success of its predecessors to set the pace for smart phones.”
However, despite creating the "Best Mobile Device", Apple still lost to HTC as they were awarded "Device Manufacturer of the Year." What mounts up to HTC's win includes "great communication and good customer service" admist "a strong portfolio of devices across many platforms."
