iPhone 4s Beginners Guide?

hey guys, my 75 year old uncle just got himself an iphone 4s. he is somewhat computer literate, but this is a huge jump for him. i am trying to find videos that teach people the ins and outs of the iphone 4s or even just ios 5. i remember when i bought my 3gs 2 years ago, apple sent me a video that was really helpful, i am trying to find something like that for him.

anybody know where to find this, i searched youtube, but couldn't find anything relevant.
