A number of key RIM customers are opting for Apple's iPhone over BlackBerrys.



NEW YORK (TheStreet) -- Halliburton(:HAL) is the latest company ditching Research In Motion's(:RIMM) employee BlackBerrys, opting instead for Apple's(:AAPL) iPhone.

The move comes after the Houston-based firm determined that Apple's iOS platform "offered the best capabilities, controls and security for application development," according to a newsletter distributed to employees.

The energy services giant's move is more bad news for embattled BlackBerry maker RIM. Dell(:DELL) said in late 2010 it intends to move all 25,000 of its employees over from BlackBerry to its own smartphones running Microsoft's(:MSFT) Windows Phone 7.

Halliburton's iPhone decision reflects a growing trend whereby large companies are gradually easing up their IT policies and allowing employees to bring their own mobile devices to work.

Apple's iOS, in particular, has caught on in the enterprise market over Google's(:GOOG) Android platform, with many businesses viewing it as more secure.

Besides Halliburton, here's a few more big names who are turning to the iPhone in the workplace.

Investment banks J.P. Morgan(:JPM), Deutsche Bank(:DB), Bank of America(:BAC), Citigroup(:C) and UBS(:UBS) reportedly weighed letting their employees use the iPhone rather than the industry-standard BlackBerry within the last year.

Apple CFO Peter Oppenheimer recently said almost all the top Fortune 500 companies "now approve and support iPhones on their networks" including Nike(:NKE) and Kimberly Clark(:KMB).
