You just picked up your iPhone 5 or updated to iOS 6, here's how to use some of the best features (and a few features you may not know). Be sure to go all the way to the end for a bonus that I have just discovered.
While you will notice that Facebook and Twitter are integrated throughout your iPhone, you can share a web page address (URL) in a number of ways. When you open a web page you want to share, tapping the share button (the box with the arrow arching out of it), brings up all the ways to share. You can send a text message with the URL, email it, print it, copy it, create a shortcut on your home screen, save it to your bookmarks, or add it to the reading list to read offline.
