Last fall, Windows Phone 8 GDR3 arrived to deliver support for 1080p resolutions and larger displays. In doing so, the platform introduced support for an extra column of Live Tiles, now with enough room to display three medium tiles (or six small tiles) in a row. Early on, we thought this mode might be coming as an option to existing devices (seeing it teased on models like the Lumia 920), but this ultimately failed to transpire. A new rumor suggests that it might finally be happening for Windows Phone 8.1, and phones with screens measuring 4.5 inches or larger would be able to partake.

At least, while that 4.5-inch rule isn’t explicitly spelled-out here, the list we get of Nokia Lumia models that both would and wouldn’t support these extra tiles is clearly split down size lines: 4.5-inch models like the Lumia 920 make the cut, while 4.3-inchers like the 820 are left out. Presumably this mode would be an optional setting, for users who just aren’t interested in crowding-up screens on the smaller side of those handsets that make the cut-off.

We also hear a little about the ability to store apps on a microSD card. Supposedly, users wanting to take advantage of this WP8.1 feature would need to have cards rated a class 6 speed or above. In cases where the inserted microSD card was not detected to meet that minimum, the app-to-SD feature would be automatically disabled.
