iPhone 3GS Continous Rebooting Issue

Rodney, give this a try. Go here and download iREB. Once you have it downloaded run it and you will find a tab REcovery Mode Loop fixer. Select your iPhone from the list and that should resolve your error. Of course this is all assuming that there is nothing elses that has happened to your phone or the you might have a battery that is going to get old. Have you tried to reset your phone yet? Press and hold the Home button and the Sleep/Wake button at the same time.Continue to hold both buttons (Ignore the "Slide to power off") until the iPhone turns off and begins to restart. Once the Apple logo appears you can let go of the button, it is now reset. Good Luck and let us know how it is going.
