I like the app... It's clean and simple. I had this problem the other night. I wanted to see stock of phones and unless you begin the process of upgrading your line, you can't do that on mobile.
Anyway, seems like there might be a creative solution here if you run your own lightweight proxy-like API so that on the surface it appears like you're not scraping Apple. It also opens the door for repeating the experience of your native app as a mobile friendly website.
