Not necessarily. My first broke largely through my own carelessness. The second, however, just fell out very shortly after I received it and after I had shown it extreme care.

I have identified likely root cause as poor tinning on some connectors. That means the solder used to secure them isn't even melding with the connector. No amount of care in the world will compensate there-- those WILL fail, no matter how gentle you treat them.

There's a good chance Nokia improved QA to ensure ALL connectors are tinned properly at some point.
