Mobile phones are very much popular in today’s time due to its usability and user friendliness. This popularity has led to the increasing sales of mobile phones. Mobile equipment’s can be divided into four categories – Nonintelligent devices (have almost no features of intelligence), cell network based mobile devices (Generally called mobile phones), smart mobile gadgets (have some modern day features other than calling) and mobile phones which have operating systems (like Android, Symbian etc.). Users of mobile phones are able to access various kind of services (through applications) anytime and anywhere. The fundamental focus here is to make applications an integral part of the environment so that mobile phone user can interact with the device and do computing on it without knowing the details.
