The msapplication-TileImage tag added by the Site Icon module doesn't seem to be enough to create a tile on WIndows Phones. Compare the tile at the bottom, center of the phone (created from a site using Jetpack's Site Icon) to the tile at the bottom left (created from this site)

The site where Windows Phone Tiles work includes other tags:
<meta name="msapplication-TileColor" content="#1e5078">
<meta name="msapplication-TileImage" content="/images/orion/icons/mstile-144x144.png">
<meta name="msapplication-config" content="/images/orion/icons/browserconfig.xml">
Following the steps on Windows's official site, it seems that both the color code and the msapplication-TileImage tag are needed. The browserconfig.xml is only there to provide extra image sizes. Here is the content of the file:
<?xml version="1.0" encoding="utf-8"?>
<browserconfig>
<msapplication>
<tile>
<square70x70logo src="/images/orion/icons/mstile-70x70.png"/>
<square150x150logo src="/images/orion/icons/mstile-150x150.png"/>
<square310x310logo src="/images/orion/icons/mstile-310x310.png"/>
<wide310x150logo src="/images/orion/icons/mstile-310x150.png"/>
<TileColor>#1e5078</TileColor>
</tile>
</msapplication>
</browserconfig>
Would it be worth trying to sample the Site Icon with Tonesque, and automatically create a color tag?
