Hello all, I've recently purchased an Iphone 4 that comes preloaded with the 4.02 OS. This is my first iphone ever.

I want to jailbreak my phone, so what i need to do is to downgrade my OS from 4.02 to 4.01.

Using TinyUmbrella, under advance option on the request version field, which version should i be choosing in order to first save my SHSH Blob?

4.1, 4.02 or 4.01

Thank you very much.
 
Unfortunately, if your phone came with 4.0.2, you cannot downgrade. Blobs for each firmware version can only be saved while Apple is still signing them. Right now, all you can save is 4.1, and wait for the next jailbreak to become available.
 
Alright, thank you for the reply. That has certainly cleared some of the questions I have. Already saved the SHSH Blob for version 4.1.
