last summer when it announced plans for its Boot to Gecko mobile OS. Now, it looks like the project has some industry support, with CTO Brenden Eich tweeting that the company will make a partner announcement at MWC this month. There are no details right now as to who might be involved, but given that developer support is already there (the operating system is based on existing web standards, after all), the hopes are that this could indicate vital operator, or even hardware manufacturer backing. Another encouraging development is the first sighting of the platform's Gaia UI, further suggesting the project might well meet its planned Q2 release target. It doesn't stray too far from the Android / iOS model that we're already familiar with, but give the source link a swipe if you want to see more.
