苹果触摸图标（iPhone视网膜）未应用-出了点问题吗？

Question

I have 4 icons for my site:

• iPhone
• iPhone Retina
• iPad
• iPad Retina

They're all working perfectly apart from iPhone retina (144x144), which is just showing the usual low-rez iphone icon (57x57). Below is my code, please tell me what I'm doing wrong.. All paths/images/sizes are correct.

Thank you.
