how to return to normal iphone?

[eddies1j2]

ok i bought an iphone and it was 1.1.2 with the new bootloader. so i downgraded to 1.1.1 for jailbreak and used the guides that said downgrade, jailbreakme.com and then upgrade. I did everthing and now have a jailbroken iphone in 1.1.2 but i want to return to the normal state, that is a not jailbroken iphone with 1.1.2 ... as if it was a new iphone out of the box... is that posible to do without doing any damage to the iphone?/

thanks in advance

yep i think, (not Sure Mind) all you do is do a iPhone restore through iTunes
