Then what you actually need is a way to bypass the password. 

Forgot iPhone 4 Password?
iPhone, by Albel.
Whether you’ve forgotten the password to your Apple iPhone 4 or somehow a lock has appeared on the center of the screen and you can’t get past it, you’ll have to reset and restore the device.

A common thing that happens is a person will leave their iPhone 4 unattended, and as a joke, somebody will set a screen password on it. This can sometimes result in the user being permanently locked out of the device.

Follow these steps to get it working again.

Note: This process will wipe all data from your iPhone 4. You may be able to sync most of the data back once you have restored it.

1. With the iPhone 4 disconnected from your computer, power it off. Press and hold the Power button on the top of the device for a few seconds, then slide the red slider. If this method doesn’t work, press and hold the Power and Home buttons for a few seconds until it goes off.

2. With the iPhone 4 off, press and hold the Home button while connecting it to the computer you registered it from. It should then power on.

3. Keep holding the Home button until you see a Connected to iTunes message appear on the screen.

4. Open iTunes and it should provide a message about an iPhone connected in Recovery Mode.

5. In iTunes, select the Summary tab and click Restore and follow the prompts.

When the process is finished, your iPhone 4 should be available again without the need for a password. http://www.macpassword.com/forgot-iphone-4-password.html
