New generation and new innovation on phone cell have marketed like Nokia smart phone and Black Berry and also from Sony Ericson like Xperia X2 have distributed their product to the market with newest technology innovations.
Phone cell technology also developed a smallest phone like on the picture below.The new creation on phone cell technology have create a strickt competition on phone cell market. Every phone cell producer try to catch market if they don't want to loose their consument.
Inovation in phone cell technology is not always purpose to sell their product, like on the above model the smallest phone actually will difficult to use. User will more difficult to dial, because the number and letter is too small and also difficult to touch. I think this innovation is just for prestige, not for their market.
