I will add a feature I recently found out about. I knew that when typing if you double tapped the space bar it would put in a period and a space to start a new sentence. What I did not know is that you could do the same thing by single tapping the space bar with two fingers at the same time.
That's a nice trick. I didn't even know about the double tapping of the spacebar.
Just got my iphone last week, but had an ipod touch for a year....didn't even know you could do screen shots with the ipod.
now....how to run apps in background? like pandora?
