Two months after Android Gingerbread was free, Nexus One users can finally update their phones to the newest Android version. "Gingerbread (Android 2.3.3) update now rolling out to Nexus S and Nexus One. Be patient, may take a few weeks for OTA to complete," informs Google. Ry Guy explains that Google "sends out OTA updates (...) incrementally to make sure that everything is going smoothly".
The good news is that Nexus One is the second Android phone efficient to Gingerbread and it's likely that the feedback from Nexus S users helped Google fix the most significant bugs. Unfortunately, Google is wedged between releasing the Android version for tablets, continuing to get better Gingerbread, developing new Android apps and services, civilizing the Android Market, so the delays are inevitable.
