According to MobileCrunch (TechCrunch), T-Mobile has confimed that Android v1.6 rollout is underway.  So for those who has the Dev Phone 1, HTC has also released the images for upgrade.  Links to images are available at: http://developer.htc.com/adp.html

For quick reference, here is the script of how to update the Android Dev phone (on a Windows machine):

1. Download the Radio and Image files from the above link
2. Download the Android 1.6 SDK and put it in the path (e.g. C:\Program Files\android-sdk-windows-1.6_r1\tools)
3. Open a command line console in Windows
4. Run: adb devices – and make sure your device is hooked up to the Windows box
5. Run: adb push <radio-image-package>.zip /sdcard/update.zip
6. Run: adb shell sync
7. Reboot the device into recovery mode by holding down the HOME key during reboot. When the device enters recovery mode, it displays a “!” icon.
8. With the recovery console displayed, open the sliding keyboard and hold down the ALT+l key combination to enable log output in the recovery console.
9. Next, hold down the ALT+s key combination to install the update. An “installing update” icon and progress bar (or a similar status message) are displayed.  When the progress bar completes, the installation is finished.
10. Press the HOME-BACK key combination to write the radio image, update the firmware, and automatically reboot. Note that if you do not use HOME-BACK at this point, the device will not load the updated radio image. After writing the radio image, the device shows a “updating firmware” icon for a few seconds and then automatically reboots in normal mode
11. Reboot and enter fastboot mode – power up the device (or reboot it) while holding down the BACK key. Hold the BACK key down until the bootloader screen is visible and shows “FASTBOOT”
12. Run: fastboot erase cache
13. Run: fastboot update <imagepackage>.zip
14. (Optional) Run: fastboot reboot

T-Mobile confirms that Android v1.6 (Donut) rollout is underway

Rumors were abound last night that T-Mobile would begin sending out the Android v1.6 update (known amongst the geekdom as “Donut”) today, and sure enough: they’ve just confirmed it.

The big changes here include a fix for a bug that would reset your phone after dialing 911 (Oops!), the new (and much prettier) market, improved voice search, a new camera interface, and homescreen search. Here’s the official word from ol’ Magenta themselves:

The rollout of Android 1.6 (Donut) to T-Mobile’s G1 and myTouch 3G customers is now underway, and provides new features and software enhancements. The update also includes an important fix for isolated instances of system reboots after dialing 911. We have worked with Google and HTC on a solution, and the rollout of Android 1.6 is being accelerated to ensure the system reboot fix is rapidly delivered to our customers.

The over-the-air update will be delivered to all G1 and myTouch customers in the coming days. Given the system reboot fix, we strongly encourage all users to install Android 1.6 when prompted to do so.

Regarding new and enhanced features, Android 1.6 includes:
* An improved Android Market experience that makes it easier to discover great applications.
* An integrated camera, camcorder, and gallery interface.
* Updated Voice Search, with faster response and deeper integration with native applications, including the ability to dial contacts.
* Updated search experience that make it easier to search various sources, such as browser bookmarks & history, contacts, and the web, directly from the home screen.

Additional details on Android 1.6 can be found at http://developer.android.com/sdk/android-1.6-highlights.html

If last night’s rumors continue to hold true, G1 owners should begin getting their updates today, and myTouch owners should start seeing it tomorrow. Let us know when you get yours!
