Hi guys, I am trying to follow the downgrade tutorial from 4.0 to 3.1.3 but I am a little confused.

When i download the 3.1.3 from the link its a zip file and when extracted its all in bits? What do i do with it all?

Is there somewhere I could download an intact 3.1.3 firmware?

Does this make sense? This downgrading stuff is all new to me im affraid.

Please help me guys, i got forced to update and now im absoulutly devo'd without my JB'n iphone!
