iOS4 intall took about 90 Minutes...

I don't know why it took so long and I don't know if this normal or not. The install process took about 90 minutes or so. Maybe my sync wire is going bad and the whole time was spent on data communication errors or something. I don't know. Read a book while watching it go, so it was not a complete waste of time.

But boy is this a good upgrade for the iPhone:

• Camera now has an electronic zoom. In the spirit of "the best camera is the one you have with you", this is a great feature which makes the camera more useful.
• Folders for grouping start up icons. Good for usability
• Mail has some upgrades which allows you to read all mail in all accounts from one view. I need to monitor a number of accounts and this is useful. At first glance, though, it's not clear how to tell which account the mail actually resides in. This would be needed to help me understand who I am when I reply.
