iPhone 4 Upgrade from 4.0.2 to 4.1

[BlackReigns]

Is it possible?

I haven't been keeping up and I read that the new Zausser theme should run on 4.1 and i'm not tech savvy enough to know if i can upgrade

If you do not need unlock and if you have 4.1 shsh blobs, then you can download your shsh file using tiny umbrella and start tss server to verify your blobs to restore to stock 4.1 fw.
