The business I work for has an AT&T account and we have been bugging them about iPhone’s release for business accounts since it was released. Finally, with news of the supposed release next week, our CEO went into the store and talked to our business account manager. He told me that the manager showed him a memo stating that iPhone’s business plan included a Summer roll-out. Not only this, but that the business account must have more than 100 phones enrolled.
This leads me to believe that Apple is waiting for a 3G iPhone release before making it an option for business/corporate accounts.
I hope this is not true, but this came straight from our AT&T store yesterday afternoon.
Edit: Boy Genius also got a similar tip from a reader. This coincides with our Mayish prediction of iPhone 3G release.
