Here are a few tips for typing on your iPhone:

• Double-click the space bar to end a sentence
  I know, this one’s pretty well known, but just in case some of you out there missed it…
• Hold down on the “.com” button to access additional domains
  You’ll have easy access to .net, .edu and .org.
• Forget about www. and .com
  When typing a URL in Safari’s address line, you don’t need to include the prefix or the suffix.
• Insert punctuation more quickly
  Press and hold the “123” button, then slide to the punctuation mark you want. It will be inserted into your text when you let go.
