Dell has announced that it is planning to replace 25,000 BlackBerry Smartphone and in its place will provide its employees with Dell devices running in Microsoft’s operating system: Windows Phone7.

A report from Bloomberg states that Bank of America and Citigroup are also testing Android Smartphones and iPhones in an effort to widen their choice of devices for their employees.

In October 2010 Apple claimed that 80% of all the Fortune 500 companies are either using or testing the iPhone which includes P&G also. Even JP Morgan Chase is also exploring the possibilities of letting workers use iPhone and Android phones for corporate email. Six months back even Standard Chartered also announced that it would be replacing the BlackBerry with the iPhone.

On the other side of the coin Dell will also offer employees devices running on Google’s Android, an operating system which is already running on some of the company’s mobile phone models.

The move by Dell is not at all surprising. It makes sense for Dell as it prefers its own product over those manufactured by others. The Texas-based technology giant claims that this move will help in cost cutting measures. The company is trying to get the customers who use BlackBerry enterprise services to switch to similar business services offered by Dell. CFO of Dell MR. Brian Gladden also admits the reason behind the switching as the company competes with RIM. The move is proposed as to be more economical for them.

The enterprise practise Director of ABI Research Dan Shey also added by saying that iPhone and then Android, the business customers have more than one choice to pick from. As each region will have a different set of competitive dynamics within a few years, as the regional installed base market shares of 50% and above will be a thing of the past.
