Believe it or not, there are people around that do not consider the cellphone the greatest technological achievement developed by mankind. For those people, Sprint is offering a series of YouTube videos that answer questions like, "What is an app?" and, "Which apps will I need to stay in shape?" For many, these will seem like the video equivalent of "Android applications for Dummies", but they do serve a purpose. Next time your aggravating neighbor or relative, the one who makes fun of you for being a cellphone fanatic, has a question about the apps on his new "Android iPhone", you can refer him to this collection.
