I know by now most people know all the little secrets about the iPhone, but I was surprised to find a few people that didn't know that you could enable Caps Lock on your iPhone.
All you have to do is go to Settings > General > Keyboard and turn on the "Enable Caps Lock" toggle. Now, when you are typing an email or text message, just double tap shift and you'll see the key highlighted in blue signifying that Caps Lock is enabled. You are now ready to SHOUT in your messages.
Any other good tips? Leave them in the comments below...
