Just after updating my G1 to 1.6 I was struck again with problems syncing contacts. Mind you it’s not a huge deal, I don’t meet 20 people a day and need there digits. It has been a common problem and was well documented based on the posts I found. The consistent fix from the Google Mobile Help forum was clearing contact data on the G1 and then sync. That worked and syncing is back.
This might be a good argument for turning on synchronization but that tends to limit battery life. If all else fails I can fall back to this but I’m hoping if I sync more often, and not make changes in both places then sync, the problem will go away. We’ll see.
