Design And Implementation Of Mobile Information Management System On Windows Mobile

By the end of the year 2009,ITU has expected that the number of mobile phone subscribers has reached 4.6 billion around the global,and by the end of this year the number of users will reach 5 billion.Although the global economy experienced a downturn phase,the needs of the users for the communication services is improving.
