Phone data is not properly escaped

[Narretz]

Moved from: #7362, as reported by @Sjlver

In step 8 of the AngularJS tutorial, a view is added to display phone information, such as carriers. This data is displayed incorrectly, for example in #/phones/motorola-atrix-4g

Availability
AT&T

The source of this problem seems to be that the JSON data itself contains the string AT&T whereas it should probably just contain AT&T, and leave the escaping to the frontend.

It might be worth discussing as part of the tutorial that AngularJS performs automatic filtering, so it's safe to pass data that contains ampersands, quotes, etc.
