I bought a used iPhone 3GS today. It came with 3.1.2/05.11.07. I jailbroke it using Blackra1n and it seems to be fine.

I would like to update it to 4.0 and have it jailbroken as well. The only concern I have is that my SHSH blobs are not backed up for 3.1.2 and from what I can tell, I can no longer do so (tried TinyUmbrella). Is there any risk for me to move to 4.0 and jailbreak? Thanks!
