My brother got an iPhone 5C yesterday and he's going to give me his old phone for Christmas. The last time I used an Apple product was in 1994, though, and I've never used a smartphone of any sort.
So what kind of cool stuff can I do with the phone when he gives it to me? I know talk/text is out, and non-wifi data is out, but I'm sure there's loads of other cool stuff?
If you have/had an iPhone 4, what did you like using it for?
EDIT: I'm not connecting it to phone service because I already have a dumbphone that works fine and is super cheap, and also my carrier apparently no longer supports the iPhone 4.
