What is wrong with my i phone?

Okay so i have the 1st generation of the i phone. So yesterday i was going on a game on the phone then out of no the screen turned black and a picture of an itunes icon with a plug in popped out. I tried hitting the home button,turning it off, or just leavin it alone for a couple of minutes but nothing happened. I waited till it was dead then i put in the charger overnight. The next day, it had the same picture of the icon and plug on the screen. Then i waited for it to be dead. Is this just because it is an old phone and it is the time to get a new phone or is it something else? Plz help!!!

If you are seeing the iTunes icon, then your phone has completely lost it's programming. Resync with iTunes using the Restore button.
