Iphone 3GS on 3.1.3 SHSH Saved Spirit

[jbreal]

Hi guys,

There is so much information that I really don't know what I should do so here is my question:

I have a Iphone 3GS bought with 3.1.3 jb on spirit SHSH saved on Cydia but now I want to jailbreak it on a more recent firmware. What should I do?

Wait for greepoison (even if we don't know if it is a fake)

or

Downgrade on 3.1.2 to be able to use Snowbreeze

or

???

What am I suppose to do ?

You have a few choices, depending on how far back your shsh blobs go back. If you have a old bootrom 3GS and have your blobs for 3.1.2 than you can jb it with blackrain then use snowbreeze to create a custom 4.1 firmware. Or you can restore it to 4.0.1 and use jailbreakme.com to jb it.
