Several Nexus One users had complained of 3G issues over the past few weeks and while Google might have fixed several of the issues that had persisted so far, few users still seem to have been facing them.
However, in a new note on the Google Support forums, the company has announced (informally though) that they shall no longer be investigating 3G connectivity issues since any persisting issues are likely to be with users with weaker 3G coverage in their area.
Here is a transcript of the message posted by a Google employee
I’ve seen some recent speculation on this thread about an OTA to improve 3G connectivity and I want to give you an update on the situation.
While we are continuing to monitor user feedback regarding the 3G performance on the Nexus One, we are no longer investigating further engineering improvements at this time.
If you are still experiencing 3G issues, we recommend that you try changing your location or even the orientation of your phone, as this may help in areas with weaker coverage.
