If you're the type who just can't wait for an update to be pushed out (erm, like some of us around here), you're in luck. You can manually apply today's update to your Nexus One, enabling multitouch and (hopefully) fixing that pesky T-Mobile 3G issue. Here's how to do it: [via Android Forums]
- Download the update from here (Google official) or here (mirror).
- Rename the file to update.zip. Note that if you're using Windows, just rename it to "update" (no quotes, of course) because it's already a zipped file.
- Copy the update.zip file onto your microSD card.
- With your Nexus One off, hold down the trackball and press the power button.
- You'll be booted into a white screen with three Android robots on skateboards. Select "Bootloader."
- On the next screen, select "Recovery."
- Your phone will reboot, giving you a picture of the Android robot and an exclamation point inside a triangle.
- Now press the power button and volume up button at the same time. It could take a couple of tries.
- Now (using the trackball this time) choose "Apply sdcard:update.zip" and let things run their course.
You may have to soft reset a couple of times after this. (I got a picture of the Android guy outside of a box. But a couple resets later and all was well.) But now multitouch is enabled, and we can sit back and relax, knowing that we have zero patience and just can't help ourselves.
