What is the significant financial impact? Have apple reported any? The phone has been out in Australia for 2 weeks and is still constantly sold out at every single phone store, with no signal problems reported at all on our cellular networks.
Unless the impact is "material" (an accounting term of art: "Information important enough to change an investor's decision" http://www.ais-cpa.com/glosa.html) then they won't be reporting it. It could be big enough to sting, and more importantly big enough to do intangible brand damage, without it being material.
