Version 3.0 has a host of useful new features:

• Full screen view:
  • With 3 fingers, do a vertical swipe up to hide the statusbar + toolbar
    
  • Another 3 finger vertical swipe up brings up the keyboard
  • Downward swipes remove the keyboard, and restore the status bar
• Cut/Copy/Paste/Undo support:
  • When you bring up the keyboard, you can type as you did earlier
  • The letters show up without darkening the main view
  • If you tap the compose button, you can now compose your message using cut, copy, and paste, as well as the autocomplete feature of the iPhone keyboard!
  • Shake the iPhone to Undo any text editing
  • Once you've composed your message -- simply tap the Send button
• Remote Copy:
  • This needs to be seen to be believed!
  • In the remote computer, select some text, and choose the Copy option (Ctrl-C, or choose Copy from the Windows menu)
  • The text will be brought into the iPhone's copy buffer, and can be pasted anywhere on the iPhone!
• Google-based login:
  • We're not 100% ready to launch this just now.  Check back in a couple of days -- this one's worth waiting for!
