ZDNet Australia is reporting that large banking corporation HSBC is planning to ditch its current fleet of Blackberrys and switch it staff over to the iPhone. The bank has around 330,000 members of staff worldwide which could equate to over 200,000 iPhone orders.

“We are actually reviewing iPhones from a HSBC Group perspective … and when I say that, I mean globally,” HSBC’s Australia and New Zealand chief information officer Brenton Hush told ZDNet Australia.

“You know, it’s a big decision, especially when you have an existing fleet out there,” he said. “But it’s definitely something we are considering from a HSBC Group perspective.”

“I think [the iPhone] would change some underlying infrastructure considerations from an enterprise perspective,” he said .”But [Apple] have been pretty smart with the design.”

ZDNet adds that HSBC has a $6 billion annual technology budget and a team of technical support staff of over 30,000.
