As for the first fact, *****.com offer 3gp videos to be downloaded. (pm me if you want to know..?)
And I know two other sites that allow you to watch research on your Ipod.
As for the others, I couldn't care less, never liked apple due to the fact that not much is supported, I simply use an Ipod because it has lots of storage and it's small, does everything that I want it to do.
