The 1Ds II is unfortunately not on DSLR Controller's device list otherwise I would suggest picking up a cheap android device:
yeah no usb, its firewire only
The camera has an USB 1.1 port however no liveview. For checking the pictures on a larger screen you could look at the program Shuttersnitch which support different brands of WiFi cards.
I was looking through the website of shuttersnitch. Thanks for the input. I guess since I'm using an iphone, i can download the app then buy some eyr-fi card so i can use it...
