I think, as a general rule, the market segment that only gets the free phone from carriers isn't really the type of customer the iPhone caters to anyways. I mean, how many people looking for the free phones are willing to add $30 per line---per month, for unlimited internet and email? Again, we are compairing Apples to Oranges. The iPhone is going to compete (and win) against most of the other smartphones out there; certainly at AT&T.
I really hate to hear people belly-ache about the TCO, when you are locked into a 2-year contract with any subsidized phone you buy. $199 is a great deal, and sales will reflect that.
That is interesting yet predictable. I wouldn't be surprised if, by July of 2010, the iPhone is the most used phone in businesss. Apple will keep doing their best to appeal to the businesss world, and it appears that they are doing more than most companies.
With the new 3G phone they wont have to open the security on the exchange server. I read that the syncronization to the exchange server will be through an activesync model. This connects to your webmail server and pulls the data directly from your webmail.companyname.com site without the need to have imap or any similar security risks in place.
We use this method with our Sprint PDA's and it works great. My company is just like yours and refuses to activate that feature for "security reasons" so they found alternate ways to do it and using activesync through the webmail server works almost as good. The main difference is you have to sync to update your mail, calendar, notes, etc.. instead of it being automatically pushed to the phone.
