Overheating I find it interesting that some said what's the point is we are on our 3rd unit. Here's the point, I am now working directly with an engineer in Cup. Apple is taking this very serious they see these low ambient temp faiures a major issue, they are currently seeing each failed overheating unit. They have also finally released an internal bulletin on the issue. Their words not mine.... "since the unit cannot be used outside in CA and TX we have an issue". They currently feel they that it can be addressed with a software update not a hardware rev... They are also testing a UV Filter screen cover. So keep the reports coming. Call Apple each time it occurs. They even go to the point to acknowledge that the 3G will bring to issue to the forefront since it generates more heat.
