If those screenshots of Android’s upcoming patch from Cupcake whet your palette for new features on the G1, here’s a video walkthrough and instructions on how to get an emulated version of Cupcake on your computer.
1. Download and install the Android SDK found here.
2. Download this zip containing new latest Android images:* android_images_sdk1.5.zip (28Mb)
3. Unpack files to a temporary location.
4. Backup the folder/tools/lib/images (is the Android SDK installation folder)
5. Replace the files ramdisk.img, system.img and userdata.img in/tools/lib/images with the files unpacked from the zip in step 3.
6. Start the emulator and wait.
There’s still no word on how long it will take before we see this on a proper device, but at least we know what to expect.
