If you're one of the many telecom/IT folks that has been able to turn down Iphone requests due to AT&T not allowing Iphones on corporate plans then you now need to come up with a new excuse, such as the lack of e-mail integration to Microsoft Exchange.
Now that AT&T has announced business plans no doubt these devices will be showing up in an enterprise near you. What impact this will have remains to be seen, perhaps it will be limited to the same creative types that want/need Macs or maybe it will become the business device of choice in the coming years.
If you're an enterprise and you decide to approve the device and/or start a pilot to approve the device please let us know how it goes.
