No he really didn't ever say "i'm sorry our product has a flaw". He was even asked point-blank if an apology was in order..."Q: Do you owe people an apology? A: People say it's the coolest phone they have ever had. But we want people to be satisfied, and they can return the company. We want investors who want a long-term view, who trust us in the long run to keep innovating."
If you call that an apology, then ok, he did.
