I saw someone make a thread about this, which has since been deemed has fake. However, this really happened to me! woke up and the activation screen was on. I tried bypassing it, but had to restore back to ios 6. Surely, I can't be alone on this. Also, just to be clear I updated without a UDID. Save your "this is why only developers should use betas" nonsense. I'm not complaining, just find it weird. Especially that it happened without me updating it.
