3GS the writing that says iPhone on the back will be silver not grey
Here's what you do
1.Make sure your phone is not plugged into the computer.
2. Put the iPhone into recovery mode (this is NOT DFU mode). Do this by
     a). Hold down both the power/sleep button and the home button until the screen turns black/off
     b). As soon as this happens release the power button but NOT the home button
     c). If done correctly then the Apple logo will appear, KEEP HOLDING THE HOME BUTTON and eventually a connect to itunes graphic will appear. You can release the home button
3. With the connect to itunes graphic on the screen, plug your phone into the computer. iTunes will start up if it is not already on, and then will say the phone needs restoring. Ignore this and COMPLETELY quit iTunes.
4. With iTunes off and the graphic still on the phone screen, hold down both the power/sleep and the home button again for 9 seconds (count 100, 200, 300...) or until the screen goes black
5. When the screen goes black release the home button straight away.
6. It will start up with the iPhone activation screen ignore this. iTunes should have started up, if not do so. Go to the iPhone tab and either resotre from backup or set up as a new phone.
