Bye bye BlackBerry?

It seems that BlackBerry could be losing its position as the corporate smartphone of choice. Bloomberg reports that large corporates, including Bank of America and Citigroup, are considering adding the iPhone to the mix of tools available to staff.  A key driver seems to come from individuals who have their own iPhone and want to use one at work. Research by Nielsen, cited by Bloomberg, backs this up.  About 42% of BlackBerry users say they want to stick with the brand when they buy a new phone but for iPhone users the rate increases to 89%.
