Hey everyone. I have a 3Gs that was on 4.2.1 with ipad BB 6.15. I was super excited for redsnow 0.9.10b1 and slipped up by restoring stock 5.0.1 firmware and not a custom one. what is my next move and did i screw up my BB? can i downgrade back to 4.2.1 and re flash BB back to 6.15? i dont have any SHSH blobs needed for a downgrade.... thank you for your help!

how do you re-flash BB?

Just jailbreak untethered your 5.0.1 firmware using redsn0w. Does your carrier still works? If so, you should be fine. I once did that to my iPhone 3GS and the baseband stayed the same to 6.15.00
