Have you tried holding the power button and the home key together. Hold until unit reboots and once apple logo appears, release both buttons. If this doesnt work try this below.

Try launching I Tunes on PC without I phone connected. Then make sure I Phone is switched off. Now hold down the home key (square at bottom of screen) Whilst still holding home key plug in your I Phone usb lead. I Tunes should identify you I Phone after few seconds and prompt " detected I Phone in recovery mode" (or similar) it should then prompt 'yes' or 'no' to do recovery. Select yes and let it start. This should resolve this issue as it did on my 3G version.
If still no luck search FAQ's section on www.apple.com
