I am enjoying a lot of facilities with my business class handset Motorola Defy and it has eased my almost all the works. But , I want to ask about the history of cell phones especially about the smart business class handsets. And I also want to know about the group that launched the first smart phone in the market. Though, it is not going to help me in any kinds of professional works, but it would really give me the idea that created ours highly beneficial gadgets. Thanks .
