My iphone 4g screen went white! (Help)! 1?

First i was on yahoo messenger on my iphone and the suddenly the screen turns white and i didn't even drop. I tried using the home button + power and it didn't work. I tried to plug it to itunes nothing happened. I Really NEED Help!

Keep It On With Out It On The Charger, And It Will Adventully Die, And Just Cut It back On

Try holding the sleep/power button down while holding the home button down for a few seconds. This should reset your iphone. If all else fails, call Apple!

Hold in the lock and home buttons at the same time for about 30 seconds and plug into iTunes. It should say it found an iPhone in recovery mode. If this does not work, your phone might have went belly up. If this is the case, time for an iPhone 5! Good luck. Also consider taking it to your carrier for help.
