I have a problem with an iPhone 3G 8GB. It was jailbroken with tons of apps. I can care less about losing all my data on it. When I boot it, it sticks on the apple logo with the spinning wheel. Every 10 minutes it reboots itself and gets stuck again on the same screen. I tried putting it in recovery mode and DFU mode but it is unresponsive. Neither the home button or power button respond. It stays like this until the battery dies. Any help?!
