Apple is only signing 4.1 for the iPhone 3G and 3GS.

You can not share shsh. They are device specific.

Apple is still signing 4.1 for the iPhone 3GS only. SHSH blobs are unique to one device's ECID only. You "can" use another's SHSH to install an ipsw however it will boot into DFU and never operate properly. So in short no.
