I have two downloads on my iPhone and they work great. You can get a TV out cable at your Apple store. It will allow you to play your iPhone downloads through your TV and will charge your phone at the same time!
One thing though, the videos are large files. My 2 videos use 1/4 of my available space. So, if you want to store lots of videos on your phone, get the iPhone with more gigabytes. My phone has only 8 GB.
Do you know yet whether they will work with the new Verizon Droid?
We haven't tested on a Verizon Droid yet.
