Many things have been made easier by the touchscreen smartphone, like navigation and fun games. But when smartphone users need to write something longer than a tweet, it can be difficult. Without a keyboard and mouse, drafting that email to your boss might take longer than you'd like.
As it turns out, a feature to quickly edit text on the iPhone has existed for a while. Simply tap and hold on the screen for a magnifying glass to appear and move it around the text as you please.
