I want an iPhone but this news sucks

So I was reading the AT & T Sales Training Workbook that was published by the iPhone and I came across some bad news for me.  I really, really want one of these phones, even if it is just for the eye candy.  I need it to work for my needs though.  One of my main needs is syncing email, calander, and tasks.  I could live by just syncing my email (because I highly doubt that the iPhone will do that) but I saw this in the workbook:

It says "If the customer is looking for a solution to connect to their corporate email account, they may need a different AT & T product".  That sucks.  It does say that it will use Yahoo! Push email to send email to the phone.  Maybe I can just have all my email forwarded to the Yahoo account.  We'll have to see but I don't like this news.  Regardless I am going to get one the morining of June 29th but I may return based on my needs.
