We just been bought out by a huuuuge company and even the IT consultant is a massive apple fan but when I first met him he told me the company would never support apple.
I have had an iPhone for a while now but they are implementing new security policies and the iPhone doesnt suit them....the cost is irrelevant really as they dont mess about, they just do things their own way and I unfortunately have to move to a blackberry now.
Could always keep the iPhone on a PAYG sim but I dont want to carry two devices and work pays all my bills so I suppose I shouldnt complain really
