Even my 1 month old son appreciates the iPhone. Incidentally, if you have an iPhone and a kid age 1-3 years old, you might want to check out the Pacifier 1 app.Available now at the iTunes Apps Store, the Pacifier 1 app cost $1.99. It has some cool games suited for your babies (1-3) and some classical songs to mold your babies mind into becoming a nice fellow someday.
Aen (my son) would love this iPhone app.
By the way, he’s listening to Incubus’ Dig. 
Wow that really is a useful list. I know what I want to do but I can see it being useful for others. Loved it! watches
