It looks like Android 2.3.3 is going to be the magic number that finally brings Gingerbread to Google’s own Nexus One. What’s more, according to the GoogleNexus Twitter account, the update is rolling out now over-the-air, but may take a few weeks to complete.
If you want to see if your Nexus One is in the first batch to get Gingerbread, open your dialer and key in *#*#CHECKIN#*#*. This will manually ping the Google servers to let them know your device is online. Within a few moments you should get a “Checkin Successful” response. If your device is eligible you should be notified that an update is available.
Only stock phones are eligible for the OTA, so if you’re running a custom ROM you’ll need to revert to both a stock ROM and the stock recovery image for the OTA to succeed.
Make sure to let us know when your update begins in the comments below!
