Nexus One owners, tonight you're getting a nice treat in the form of the incremental Gingerbread update 2.3.4, previously available only to Nexus S owners. To recap, the main feature in this release is the video and audio enabled Google Talk , although since the N1 lacks a front-facing camera, it's not going to be as useful as it was for the Nexus S.

Update: Err, looks like there is no video or audio support in this release at all, according to those of you with Nexus Ones. Why Google didn't just disable the phone's camera and left it a one-way video and two-way audio is beyond me, but at this point you may as well try the Gtalk version that was extracted from the Nexus S for everyone with Gingerbread to play with.

Additionally, the following issues should now be fixed:

Battery life: some users let us know that their batteries didn’t seem to be lasting as long; battery life should be improved for these folks.

Installation instructions

Note: If you don’t have GRI40 (2.3.3) and instead somehow still have FRG83G (2.2.2), then head over here and install GRI40 first, then proceed below.

To download and apply the update to your Nexus One manually, follow the following steps:

Download the update file GRJ22-from-GRI40 and rename it to update.zip (make sure it’s named update.zip and not update.zip.zip if you’re using Windows and have it set to hide file extensions). Move the file to your SD card’s root using your favorite method – the easiest way is probably mounting the phone as disk using a USB cable. Reboot your phone and when it starts booting back up, hold down the Power and Volume Down buttons. If you see Bootloader, select it. Select Recovery. The phone will reboot into recovery but first it’ll show an exclamation point and a triangle. At this point, mash the Power and Volume Up buttons a few times until the recovery screen shows up. Select Apply sdcard update.zip, which should start the update process. Reboot and enjoy Android 2.3.4.

Thanks, Omar!
