1) learning how to program in Objective C 2) learning how to use Xcode (probably one of the worst IDEs I've ever used) 3) learning how to use the specific parts of the iPhone like iteracting with the camera, etc.
There will be a lot of issues to deal with, such as accessing the camera, storing the photo, uploading it to the web site, etc, that are non-trivial. Without a knowledge of C/C++, it might take you on the order of months, not days.
I picked up "Beginning iPhone 4 Development" and was new to both iPhone develoment and MacOS. It took me about 2 weeks to get a working app that just posted text to a Google App Engine backend, although a lot of progress was made over 1 weekend of straight coding and playing around. My biggest frustration was learning how to use Xcode, but I basically just followed the book and it ended up being a pretty good tutorial.
I don't want to be a hater, but $50 for a video tutorial that promises to teach you iPhone development in under 1 hr sounds unlikely. There are A LOT of details that need to be addressed, and I feel like the "Beginning iPhone 4 Development" book is pretty damn good as an introduction, so that's probably money better spent.
