I accidentally updated an iPhone 4 to iOS 6.0 and lost the untethered jailbreak. Is there any way to downgrade back to iOS 5.x without having saved SHSH blobs, and is it possible to use blobs from another device?

It is not possible to downgrade an iPhone 4 from iOS 6.0 to iOS 5.x without your own saved SHSH blobs. SHSH blobs are digital signatures unique to each specific device and cannot be shared or transferred between different iPhones. If you do not have your own blobs saved for the firmware version you want to install, Apple's servers will not authorize the restoration. While there are some advanced tethered downgrade methods or dual-booting utilities available for the iPhone 4 because of the Limera1n hardware exploit, they generally require a computer to boot and do not provide a standard untethered experience. For a normal, permanent downgrade to iOS 5.x, your unique SHSH blobs are strictly required.

Without your blobs for the firmware you want to downgrade to there is no way to downgrade. Blobs are unique to your device so 'Borrowing' them off someone else would not work.
