How to Preserve BB and FW

[Wicked1]

I am JB'n on Greenpoison running an iP4 with 4.1 FW 02.10.04, how can I store my BB and FW so if I had to restore I can go back to this version?

I do not remember where the directions were on this site?

Thanks

You can't. It's too late for you to get the SHSH blobs for 4.1.
D/l Tiny Umbrella and start saving your blobs for future proofing.

I agree.
Also there's no point on preserving your baseband or 4.1 blobs anyway.
Use TU to start saving your 4.2.1 shsh's.
