iPhone is stuck on apple logo… =

There's a way to fix that. But with the method I know, you will loose all your data. First enter Recovery mode. Here is how. Disconnect the USB cable from your iPhone, but leave the other side connected to your Mac or PC, then launch iTunes on your PC. Press and hold down the Home and Sleep/Power button on the top of the iPhone to turn off the iPhone. Press and continue to hold the Home button while you reconnect the USB cable to your iPhone, this will cause the iPhone to turn on. Continue to hold the Home button until an alert message in iTunes informing you
that an iPhone in recovery mode has been detected (or until you see the iTunes logo on your iPhone.) Then select restore from your PC and wait till it downloads the firmware and restores your iPhone.
