Here is another example of the iPhone's integration with your business office:
Last night while we were shooting a wedding, I could not remember how many hours the client had booked us for. Out comes the iPhone and using Vodafone free monthly data I connect to my iDisk using MobileFiles.
For those who don't know what the iDisk is and what it has to do with the iPhone: It is a service provided by Apple through MobileMe that provides you with an Internet hard drive that can be accessed by any device: a desktop computer (an Internet connection suffices), a laptop or your iPhone, provided you have a program like MobileFiles installed. I put all my important work stuff on iDisk, contracts, business plans, etc. It's like a hard drive that is the same and always up to date on any computer you use.
So out comes the iPhone and it connects to my iDisk through MobileFiles. Voilà. In a matter of seconds I downloaded the contract that was signed by the client and which I had scanned and saved on my iDisk, to my iPhone's screen.
Then last night I also couldn't remember the rate we pay our assistant videographer. Again out came the iPhone, and in a matter of seconds I had connected to our online book keeping software, Kashflow, and found out how much we pay him. All that with the iPhone's inbuilt Internet browser, Safari.
There are many occasions when I feel I have my whole office in my pocket, simply by having the iPhone handy.
