Shut Down

I had a great day with my iPhone, taking pictures, sending and receiving e-mails from the Iron Range of Northern Minnesota, showing off the web on wifi in a coffee shop and getting directions home when late in the day, took some great shots in an old iron mine and headed for home. After I charged it up, it shut down as I listened to my Favorite Bob Dylan songs.
That was two hours ago and still know life. What's up? Any ideas?:(

Try holding the sleep key (on the top of the phone) and the home key down at the same time for a few seconds. This forces a reboot of the phone and usually will fix a problem such as you're having.
