Reports are trickling in that the next Android firmware – officially designated Android 1.6 but more lovingly referred to as 'Donut' (all Android updates so far have been named after sweet, yummy snacks) – is now finding its way to people’s phones thanks to the wonder of OTA (Over The Air) technology.

According to TmoNews it looks like a select few lucky North American G1 owners are getting to dine on Donut, with T-Mobile choosing to only update a few phones as a test to ensure that the new software doesn’t turn handsets into expensive bricks.

However, reports suggest that the mobile phone operator is intending to roll out the update across all of its branded Android phones over the next few weeks. We assume that UK-based users will be getting similar treatment around the same time.

Of course, if you own an Android device that hasn’t been purchased via T-Mobile then you’ll have to wait for the rather less glamorous option of installing the update manually.

Donut is mainly focused on providing a massively improved Marketplace experience, with a better layout, superior navigation and (finally) screenshots to illustrate what each app looks like. It will also come with enhanced support for OpenGL ES 1.1, which should mean we’ll start to see more 3D games.

No doubt you’re already staring at your Android phone in expectation of the OTA update arriving, but in the meantime here’s some footage of that delicious Donut in action. Enjoy, this one's not fattening:
