Hi,

I have a carrier unlocked (contract expired) iPhone 4 (4.12.02) on iOS 6.0.1. I have the SHSH blobs for 5.1.1 and I was wondering if I downgrade will I lose the unlock or any other potential problems that can arise from downgrading.

Any thoughts would be appreciated.

Thanks!

You won't lose the unlock. If you want to restore to 5.1.1, you'll need to use redsn0w's restore option instead of iTunes.
