Word is spreading quickly, and not much verification has been provided, so file this one under “Rumor” for now. However, it appears a user was able to go from no 3G connectivity for 10 days to permanent 3G signal even after some reboots. The fix from Kevin of JKontherun involves allowing the Nexus One to automatically select it’s network. Yeah, that sounds like a good plan. To do this, go into “Settings”, “Wireless and Networks”, choose “Mobile Networks” and go into “Network Operators” section and allow the phone to look for a network. I’d try this myself, but alas, I’m without a Nexus One.
If you have a Nexus One and were having 3G issues, did you try this and is it working for you?
