So you like taking long walks and writing emails, but can't seem to do both at the same time because you might trip on something? If you're an iPhone owner, you're in luck because the Email'n'Walk app will allow you to do just what is says. We're not sure why this was not created earlier; seeing all it had to do was display video from the camera while using the email app. There is a transparent view on screen showing what is in front of you while casually walking. So now you send an email without the worry of walking into someone or tripping over something. Let's face it, this might be one of the greatest things to aid some people! But if they can implement this with SMS, then it might truly be a savior.
