Given the fact the cell phone companies do not offer insurance on the iPhone, and with it’s pricey price tag; I would have to say that based on that fact alone the iPhone isn’t ready for the Enterprise. I’ve seen high level managers break phones monthly. With cell phone insurance that’s no big deal, they have no phone for a day or two while it’s repaired. With an iPhone there’s a few hundred dollar price tag every time the phone is broken. A company which 200 phones could be shelling out a couple of thousand dollars per month for replacement phones.
