Imagine the feeling when the application you installed in your mobile phone has completely vanished! There is a high possibility of this happening, courtesy the “kill switch.”

This killer is being used in many areas in various forms:

A “dad man’s switch” stops vehicles and machines, in case the operator has problems and loses control. A kill switch at pumping stations is used for gasoline pumps and other devices that pump flammable or explosive chemicals. Even treadmills have a “safety key” that comes into action when a person trips or falls.

In IT language, a kill switch is a security measure used to shut off a device or a program. Where software is concerned, the software is rendered useless to users if it is pirated and not obtained in the right way.

Kill Switch in Apple and Google

Coming to the mobile phone segment, kill switch has been incorporated by Apple in the iPhone. Through these switches, the company has the capability of uninstalling or deleting any application that they think should not be on your phone.

This was not something Apple made a whole lot of noise about and preferred to let silence rule – until people discovered it for themselves and the world was up in arms.

The iPhone quietly connects to Apple’s servers to check an application blacklist, and disable any apps that should not be there. (more…)

Recent sales numbers of the iPhone and the BlackBerry have surprised people in the know. The reason for the surprise is that BlackBerry has always been considered to be synonymous with a business phone, but now the iPhone sold more.

Earlier, Steve Jobs announced that the iPhone would support Microsoft Exchange ActiveSync, which will enable users to synchronize their calendar and contacts along with receiving push mail on their iPhones. This announcement had many critics remarking that Apple is attempting to just grab a small slice of one of the most lucrative markets – the enterprise phone segment and nothing more will come out of it. Of course, diehard Apple fans are never deterred by these comments and have always counted on the iPhone to make a difference in this market, where enterprise phone segment is the arena of players such as the BlackBerry and the Nokia E-series.

The sales reports of smartphones reveal that Nokia still ruled, followed by Apple and then BlackBerry. This is a great achievement for Apple, considering that the iPhone does not have as many models as the other two. Another fact is that the competition has released high-profile devices recently too, such as Nokia’s E71 and RIM’s Bold. However, a device that has not been considered to be a suitable choice for enterprise use until now has won hands down. (more…)
