If you don’t have an unlocked dev phone G1, you’re going to have to wait a few weeks to get Donut running on your machine. The ROM is hard to find and it doesn’t work for rooted G1 owners. Fortunately, the fact that Donut is already out among the developer community means it shouldn’t be too long before a version is out that the rest of us can use.

And what can we expect from this update to Android’s UI? For one thing, Android now handles playing and storing music files a lot better. The playlist interface has improved dramatically, and there’s now a shortcut to the media player right under the google search bar on the Android desktop. The Internet browser, the calendar, and a whole host of other bits of the Android UI have received significant updates.

 an Android dev named Haykuro managed to get a hold of a ROM of the new version of Android for the HTC Hero. Now, thanks to another developer, we’ve got a video of the leaked build that shows us the widget functionality we can expect out of the upcoming Hero and probably G1.2 as well.

It gives us a pretty good look at how the the latest version of Android will perform, at least on the Hero. I have to say, I am highly impressed. For one thing, the new widgets look great. They’re all well-designed and you can tell at a glance exactly what information they have for you.

The new Android UI starts off as very bare-bones, but by filling your home screen up with widgets you turn it into a glittering utopia of pretty gadgets. Just from this video, we can see an excellent-looking Twitter feed, a bookmark section, a great little weather tool, a scrolling contact list with contact photos, and a music player.

With all of those on, the UI gets pretty filled up, but never crowded. Just like in the current Android build, you can slide left or right to give yourself more space, and access the rest of your programs. Honestly, it looks to me like Android’s gotten even easier to use. It really is a great little touch screen UI, and HTC is taking advantage of Android’s strengths with this new ‘donut’ build.

Those of you that look at the iconic Android clock on your T-Mobile G1 or the HTC Magic and think: ‘that’s so 2008′, get ready to pick up the uber-skinned HTC Hero ROM instead.

The clever chaps over at the XDA developers forum have managed to put together a working port that makes your current, bog-standard Android device into a next generation behemoth.

Well, that is until the HTC Hero actually hits the shops in the not-too-distant-future, complete with super widget gallery and some kind of space-age buttons that might make you feel like you’re aboard some intergalactic space ship. Or not, your call.

Wrangler

The only problem is you’ll need to be a pretty clued-up developer / code wrangler to get this thing on your phone – we’re talking flashing the device, connecting up the debugger, the works.

So if you’ve only just committed to an HTC Magic for two years on £40-odd a month, you might want to think twice before breaking it through your ham-fisted porting efforts.

But on the plus side, the leak means it’s unlikely we’ll have to wait too long for the HTC Hero, so you can at least upgrade to the latest version of the Android gang if you’re lumbered with nothing more than a shiny white brick.

Is Android Open Source?

Android was built from the ground-up to enable developers to create compelling mobile applications that take full advantage of all a handset has to offer. It was built to be truly open. For example, an application can call upon any of the phone’s core functionality such as making calls, sending text messages, or using the camera, allowing developers to create richer and more cohesive experiences for users. Android is built on the open Linux Kernel. Furthermore, it utilizes a custom virtual machine that was designed to optimize memory and hardware resources in a mobile environment. Android is open source; it can be liberally extended to incorporate new cutting edge technologies as they emerge. The platform will continue to evolve as the developer community works together to build innovative mobile applications.

All applications are created equal?

Android does not differentiate between the phone’s core applications and third-party applications. They can all be built to have equal access to a phone’s capabilities providing users with a broad spectrum of applications and services. With devices built on the Android Platform, users are able to fully tailor the phone to their interests. They can swap out the phone’s homescreen, the style of the dialer, or any of the applications. They can even instruct their phones to use their favorite photo viewing application to handle the viewing of all photos.

Breaking down application boundaries?

Android breaks down the barriers to building new and innovative applications. For example, a developer can combine information from the web with data on an individual’s mobile phone — such as the user’s contacts, calendar, or geographic location — to provide a more relevant user experience. With Android, a developer can build an application that enables users to view the location of their friends and be alerted when they are in the vicinity giving them a chance to connect.

Fast & easy application development?

Android provides access to a wide range of useful libraries and tools that can be used to build rich applications. For example, Android enables developers to obtain the location of the device, and allows devices to communicate with one another enabling rich peer-to-peer social applications. In addition, Android includes a full set of tools that have been built from the ground up alongside the platform providing developers with high productivity and deep insight into their applications.
