Nexus One Upgrade To Android 2.3.3

This afternoon I received the notification on my Nexus One that the upgrade to Gingerbread was available for download and installation. The notification appears to be a little different and I don’t know if that is because my Nexus One is only connected to WiFi. By receiving the notification, I confirmed that upgrades are being pushed by Google to phones over WiFi as well as cellular networks.
In previous OTA upgrades, the update downloaded automatically to my phone and the notification stated that the update was on my phone and ready to be installed. In the case with this upgrade to Gingerbread, I had to first initiate the download of the update before beginning installation.
The installation process was consistent with prior upgrades once it got past the download step. After the installation takes place the phone reboots and the start up process is longer than normal, making for a few tense moments. When the phone booted up, I confirmed that Android 2.3.3 is installed, build GRI40.
One of the first things that I tested after the upgrade was Google Voice, given the reports of people having problems with it not working after manually upgrading their phones. I can report that in my case, I did not experience the problems that have been reported, and I am able to access my Google Voice account, receive and send text messages.
One odd thing I did notice immediately after the upgrade is that the Android Market appeared to revert to the previous version. However, about thirty minutes later I opened the Market again, and this time the latest version appeared. It appears that the new Android Market is not included in the upgrade package and is distributed separately.
The bottom line is that the Android 2.3.3 upgrade went smoothly on my Nexus One. So far I am seeing no problems with any of my apps after the upgrade, and the overall performance of the phone seems to be a bit faster.
