This is cool. No, this is way cool! How often have you wished you could send a friend or colleague a snap shot of your iPhone with a new application installed or tried to help them with a setting?
Now you can take a print screen of your iPhone!
On the screen you wish to send them, just hold down the Home button and then press the power button. You will hear the iPhone take a snapshot.
If you now go to your photos, you will a screenshot of your iPhone which you can either download or e-mail! So cool.
