DigiTimes has been canvassing its manufacturing industry sources again, and today it's managed to extract some intel regarding Apple's typically secretive supply chain. Steve Jobs' team are said to have purchased between 200 and 300 glass-cutting machines, specifically in order to use them to slice up curved glass display covers for the iPhone 5. This move has apparently been in an effort to accelerate production, with glass makers reportedly showing a reluctance to buy the machinery themselves due to its prohibitive cost. Lest you think this sense of urgency might accelerate the iPhone 5 from its earlier-rumored September launch, DigiTimes also reports that yields of curved glass are not yet good enough to start using said fancy machines. So the iPhone may be headed for the same curvacious look as we've already seen on Dell's Venue and HTC's Sensation (or maybe even the concavity of the Nexus S), but as is Apple's wont, it looks like that will be done with a tailor-made, custom solution. At least those Cupertino designers have a couple of generations of curved iPod nano screens under their belt, giving them a good idea of how to handle the atypical glass frontage. Now if we could just have a good idea of when this phone will actually be on sale...
