I continue to use my BlackBerry as a business phone, but the iPhone is now my personal phone. I don't use it for business though I do use the media player during work-related transit. The two devices cater to two different parts of my life: work and home.

I don't think the iPhone is a BlackBerry killer. The devices are meant for two different ends of the market. For instance, I can't dash out emails on my iPhone in the quick-fire way that I can on the BlackBerry, but I also can't check soccer scores as easily or watch the latest crazy YouTube video on my BlackBerry the way I can using the iPhone.

We don't currently support iPhones at Direct Energy. In fact, we don't support any phones except BlackBerrys, as we've invested significant funds in our BlackBerry enterprise server and related security measures, and we trust that the server is reliable and well-secured. It remains to be seen if there are any major security issues associated with iPhone use. I thought Apple did a good job handling the few "scares" that were noticed early on by quickly applying patches.

I think the iPhone could be used as a business device, but it would probably be best suited for corporate environments with Mac computers so that users could easily sync calendars, etc. In order for the iPhone to be taken seriously as a business device, Apple needs to compete head to head with RIM, and to do that it would need to offer a corporate push e-mail solution that could be easily integrated with most organizations' Microsoft e-mail environments.
