I totally agree with your observation. I've been there in last Dec and this Jan. Probably the hostile sentiment is even stronger towards Canada (Which traditionally most Chinese see as a friendly country partially because of a couple of famous Canadian who are almost unknown to Canadian themselves.) than US. Since I'm Chinese Canadian, the topic was always brought up during dinner/lunch with friends.

However I'm not sure if the boycott really has a big impact on sales. The consumers quite pragmatic when they spend their own hard-earned money even the sentiment is really strong as you observed. In China there are cut-throat competitions across all markets. Mobile phone market is one of them. There are quite a few smartphone manufacturers fighting for market share. Some used-to-be-good companies could not survive but the news only limited in China. Without boycott Apple sales still could go down because of competition.
