How I can remove the password on the 32 GB 3G iPhone running 3.1.3?

So my friend wants to sell a 32 GB 3G iPhone bought on eBay. He says his ideal, but the only problem is that he knows the password of the slide to "unlock" screen. which means that it is useless unless you can disable or circumvent the code without knowing the code. So … I was wondering if you just plug it into the CPU and restore from iTunes to remove the password? Otherwise, how I can remove the password? is also a way to do this without erasing all data on the phone? ** The most important thing is to get rid access code for the phone use

Connect your phone to your computer and start iTunes. Select the phone. Click Restore. Wait that the code will be cleared and all staff, so be wiped off the phone. This is to prevent theft of personal data from a stolen phone. If you have a more young / old iPhone, you can save and restore previously after a factory reset.
