Still possible to JB a 3G on 4.1?

[autopsytheclown]

I have had 2 iPhone 4's for awhile and my old 8GB 3G and 16gb 3G have been collecting dust so I want to JB & unlock them to sell. When I google JB 4.1 and click on links it brings me to the JB's available for the latest OS. Can someone tell me where to go & what to use to JB my old iphones? Thanks
