Currently created mobile applications can not run without Internet connection. We can provide unlimited number of usage examples of data transmission in applications. We are only limited by our imagination. By implementing this type of solution in applications, we very often forget about small thing, that network check query can be performed.

At the moment there is no phone on the market that meet this condition. Theoretically, we should not worry. However, according to the information from Microsoft the next generation operating system Windows Phone Tango should already allow for the production of low-budget phones with less memory. […]
