thing is this.. it's not as if the factory worker shows up in the morning, begins their task of making the display, their neighbor makes the camera, etc... then at the end of the day, a phone has been made.
an iPhone is being made all over the world
• Chipsets and Processors ....(S.Korea / Taiwan)
• Flash memory ..................(Japan / S.Korea)
• Gyroscope .......................(France / Italy)
• Touch ID .........................(Taiwan)
• Battery ...........................(S.Korea)
• Accelerometer .................(Germany / U.S.)
• Camera ...........................(Japan / U.S. / Taiwan)
• Display ...........................(Japan / Taiwan)
• Glass ..............................(U.S.)
• NFC ................................(Netherlands)
(probably not exactly factual.. especially if the OLED displays are coming from Samsung(S.Korea).. but close enough to make the point)
most of what Foxconn (China) does is the main chassis assembly..
so when we hear something like "this amount of phones are being made per day", it really makes zero sense in how most people will interpret that.. some parts of it were made last year, some last month, etc.

10,000 units a day?
who knows, maybe that means they've been shrink wrapping 10,000 boxed units (ie- THE final product) of them per day up till now.. but they could easily shrink-wrap a million of them in a day.. it's just that they haven't as they haven't needed to.. once the final OS (for example) is installed on them, then the dude pushes the button and the entire lot gets wrapped that day..
10,000 units per day, going through some sort of final process, could be irrelevant info as to whether or not there will be millions of phones ready on launch day.. but by the time the news makes it to the consumers reading rumor sites, the report, while possibly factual, has been skewed to make it seem as if there's a huge shortage and/or problem..
we just have no way of knowing what's meant by 10k/day.. none.
and it's such a
ridiculously low number for the way many will read it as (omg- there will only be 325,000 phones available in November

)... it just makes no sense. none.. which means, even it the report is true, it's being misconstrued beyond recognition by the time it's processed by consumer rumor readers.
