I got my iPhone 4

I got my iPhone 4 :) and have been using for more than a month.
The transition to iPhone 4 for iPhone 3GS is quite smooth.

I only need to sync with iTunes which backup all my data. When I got my new iPhone 4, I just have to plug-in and sync with iTunes. I choose restore and everything is copy to my new iPhone 4.
However as I got about 30GB of data, it took quite a while to copy.

Once done, everything is restore to my new iPhone like the old iPhone 3GS.
Everything, except the password for email accounts which I have to key in again.
