Question for anyone who's been able to try it (unfortunately... or perhaps fortunately all my phones are carrier unlocked).
I'd assume that upgrading from Win 8.1 -> Win 10 would preserve any carrier locks, but assuming locks are enforced at the OS level, a revert from Win 10 -> Win 8.1 should wipe any carrier specific information (since the revert process uses a stock build and doesn't retain any configuration).
Anyone given it a shot? Has it worked? Apologies if this has already been asked, I could only find information from the Lumia 920 days prior to the insider program and recovery tool.
