If you saved shsh before August 19 or jailbreaked before then and started Cydia once, you have shsh stored on Cydia. With stored shsh for old firmware, you can downgrade to that version. If you bought a new phone after August 19 that was never jailbroken, you're out of luck. No way to downgrade an iPhone 4 then.
