Did the pinephone 1.2a board undergo certifications?

Or was certification of the 1.2 boards "good enough"?

PCB v1.2a is identical to v1.2 with two components removed replaced. There was no need for the device to be re-certified again.

Just out of curiosity, do you know what makes a change significant enough to trigger recertification?

Any change to major components (ICs, transformers, antenna design) that leads to different functioning or specifications. There's a bit of info on this page for a company that helps clients certify (there is a section or two specifically mentioning licensed devices like mobile phones):

Thank you. That makes sense to me that the FCC, at least, may be satisfied as long as you aren’t doing anything to the radio or maybe likely interference sources.
