When someone new asks to see what an iPhone can do, all of us have a list of apps prepared to wow them. Some of these apps may be useful, some may be beautiful, and some may have changed our lives. Star Walk is a gorgeous, dynamic application that, while it may not be technically useful to some, will tease your eyes skyward on clear, starry nights.

When connected to the Internet you can use Wikipedia Mobile to search Wikipedia for articles, which can then be saved to you’re iPhone for offline viewing. Pages retain their original formatting and can be searched for words or phrases, but the app has no built-in zoom, nor does it offer bookmarking or annotation capabilities. Regardless, it’s a great way to create a library of articles conventiently available whether you have connectivity or not.

WikiMe is a great application designed to find Wikipedia articles about your current location.
