Motorola A920 Communicator is the first dual 2.5G/3G device based on the Symbian operating system and the UIQ user interface. It provides full phone and PDA functionality and takes advantage of modern, advanced 3G services like video calls or watching streaming video at 3G transfer speeds and nearly broadcast quality. We would call it a perfect PDA/smartphone if not the certification mechanism preventing users from taking advantage of hundreds of exisiting UIQ applications and making it difficult for freeware/shareware developers to offer new programs by forcing them to pass the 3's testing and certification process (and most probably pay for it).
