answer:Where’s my Water – puzzle game, ever expanding with new levels every month or so Angry Birds – (if you don’t know what this is, welcome to coming out of the cave!) Words With Friends – Scrabble-like game played online with friends (or strangers) one move at a time Facebook/AIM/Twitter/LinkedIn – mobile app versions of those respective websites Grocery Gadget – store your grocery list, update it whenever you realize you’re out of something, then take it to the store and check off each purchase as you put it in your cart. Pandora – give it a song or two, and it creates a custom playlist of similar songs that it thinks you’ll like, for free. ePhotoChest – a convenient password-protected location to store photos you want available to you on your iPhone, but that you don’t want someone who randomly picks up your phone to be able to see NetFlix – watch your streaming library right on your phone – or buy an HDMI adapter and connect your phone to a TV (like at a hotel or friend’s house) when you’re not at home and watch your library that way. I’m like 90% sure that all of the above are either free or have a “lite” version that is free (either ad-supported or limited functionality)
