Signing older firmware versions

Earlier today, Apple accidentally started signing older firmware versions of iOS, effectively letting people downgrade their devices at will. This was just a temporary hiccup as merely an hour later, Apple closed the signing of all these older iOS versions again.

Yet some readers have been able to downgrade their devices, and we would like to hear your stories.

Were you able to downgrade your iPhone or iPad?

If so, to what version of iOS did you downgrade to, and what are your intentions going forward?
