More iPhone leaks?

Engadget (God where would I be without Engadget?!) is reporting a leaked iPhone sales training manual for AT&T staff. Lists some new features, new to me at least: synching with Address Book through iTunes, which makes sense. However, if this was to truly replace my Treo 680, it would need to synch with my .mac account in full. I guess we'll all just have to wait until the WWDC or even June 29th to find out about all of the iPhones features. And limitations?...

I hoping that by the time this is launched in UK/Europe, any bugs or launch problems will be ironed out. And that I won't have to sell my soul to another mobile provider to get one. I'm in the upgrade period with Orange (signified by dozens of unsolicited sales calls offering me a new handset...and contract renewal) and I'm notorious for picking up the latest handset each summer, being disappointed, then dumping it and returning to a Treo. Oh well, there's always eBay.
