I realize it's easy to miss explanations in a big thread like this so I'll repeat (with additional detail): - no such thing as "solder being too strong". If done properly solder joints actually form an alloy between the solder and two connected materials and is by design meant to be as resistant to breakage as possible. - in the expected life of these products, there should be no "expected hard failure mode" for this connector. Soft failure is a different story, and would involve damage to the internals (like breaking the plastic tab inside). - the problem here is not solder but the copper plating. It is coming free of the printed circuit board (PCB) much too easily. The root cause fault is most likely with the PCB manufacturer, not Nokia (materials suppliers are supposed to guarantee their products' quality). However, I'm still of the opinion Nokia made a bad decision going with a surface mount connector. Even with copper plating issues, we would probably never have seen this defect with a through-hole mount.
