i am having an issue with most of my new sites which use H5BP when viewed from Windows Phone 7 (or 7.5). The problem is that this HTML tag in the site's source

```
<meta name="viewport" content="width=device-width, initial-scale=1.0" />

```

which should actually support different mobile devices, prevents the user of a mobile device (in our case Windows Phone 7 or greater user) to zoom in on the text (and the site itself).

Using this tag the mobile browser will adjust the size of the site according to the mobile viewport (i.e. mobile screen width and height). However, the problem is, when the user tries to zoom in on the text using the zoom-in gesture, the zooming doesn't work. It tries to zoom in but quickly returns to the initial width. 

Has anyone else noticed this problem and if so, what is the solution?
