I Forgot My iPhone 4 Password?

I have an iPhone 4 and I forgot the 4 digit password

When I connect it to iTunes, it says I need to put the pass on the iPhone to access the data on iTunes

Is there another way of resetting the whole iPhone 4?

I don't want to jailbreak, just reset it

Iphone query (Iphone 3GS vs Iphone 4G)?

(yes I buy my own gifts) I want to get the Iphone 3GS because I simply want to use the song capabilities and a phone, the camera and other apps are just a bonus. Should I get a 3gs instead of a 4? I also am not excited about the AT&T and I don't want to pay an Arm and a Leg for a plan and phone.
