    My Iphone 4 came yest. it is on 4.1. I got the SHSH file from tiny umbrella on 4.1. Can I now downgrade to 4.0.1 to JB.

    Do the SHSH files change with each new FW upgrade?

    You have to have the firmware you want to downgrade to's SHSH... not the current firmware

    You can only install the firmware you have SHSH files saved for. Thus, 4.1 SHSH = 4.1 firmware only. If you haves 4.0.1 SHSH files, you can downgraded to 4.0.1. SHSH are unique to each iphone + firmware version. Thus, answer is NO.

    No, you cannot downgrade or JB your device at the moment.
