A few hours back we told you about a new Lumia 920 update that had surfaced on the Nokia Care Suite, one which finally gave users a way to manage the storage space taken open by their “other” files. That’s just the tip of the iceberg, as it turns out, and since then we’ve gotten a bunch of new, interesting details on this software build.

Looking for this 1308 firmware in Navifirm has revealed that this is apparently an in-testing beta version of the anticipated GDR2 Windows Phone 8 release, the one we first saw mentioned alongside the HTC Tiara, and has been rumored for distribution in May. This doesn’t necessarily mean that we’ll see it arrive before May, but if tests are already underway, you never know.

As for more features, beyond the new cache-clearing controls it looks like the 920 is going to get some additional display calibration settings. These allow users to adjust color saturation and color temperature, in addition to changing brightness. The changes are included in a new display+touch app from Nokia, but aren’t yet enabled; the combination of the new apps and 1308 appears necessary to activate them.
