Strange solution for iOS 4.3 Error 9 got at restoring IPhone firmware

After my iPhone 4 was stuck between iOS 4.3 installation failure and restoring of iOS 4.2.1 Apple Service men tested it and confirmed a hardware problem. Now Im given brand new one.
From what I see another guy had reported same here:

Some other people also reported encounter with same problem - Error 9 during Restore at restoring iPhone firmware.
The solution is the best for the customers, but to me it sounds very strange that a software update can cause hardware damage. There is something fishy here.
Anyway, affected fellows: Do not waste your time. Go to nearest Apple Service.
