I've searched for this the last two days and didn't got anything, does anyone know a way to support static wide tiles out-of-the-box in a Windows Phone 7.1 ( 7.8 ) app, using WMAppManifest.xml ?

The only thing I've found about this is this msdn page, "Adding Windows Phone 8 and 7.8 Tile functionality to Windows Phone OS 7.1 apps", which as far as I know doesn't do what I want.

On another note, found this now: Windows Phone - Double Width Tile

But this didn't pass the certification, does anyone know if with Windows Phone 7.8 this will be accepted?

Thanks in advance !
