correction.
iPhone 2G DO NOT have online payloader security can downgrade firmware part .
iPhone 3G DO NOT have online payloader security can downgrade firmware part .
iPhone 3Gs have online payloader security you CAN NOT downgrade firmware part IF YOU DO NOT HAVE ECID backup at cydia server or locally.
iPhone 4G have online payloader security you CAN NOT downgrade firmware part IF YOU DO NOT HAVE ECID backup at cydia server or locally.

iPhone 4G 4.0.2 have online payloader security you CAN NOT downgrade firmware part at any condition at moment.

this is my experience may possible i can be wrong some time.
