Sister has passed on an iPhone 4, iOS 5.1.1 to jailbreak and unlock but hasnt got the original sim, and before some says it. Its not nicked 
This YouTube seems to think its possible, although as you can see the guy is using a SIM for it.
I can select the .ispw etc and redsn0w says its done, but it just hangs on the apple logo
