By now, you're probably aware that Apple's Sapphire provider GT Advanced went belly-up a few weeks ago. If you're not, we encourage you to click links in this article and in our timeline below, as the meltdown is both contextual and interesting. After previously noting the deal they struck with Apple was unfair, GT Advanced is now detailing their feelings. In retrospect, GT Advanced says they're not sure Apple's original offer was ever really honest, and insists they were insulted through the process. According to GT Advanced, Apple originally approached them to purchase a massive quantity of furnaces to grow the Sapphire glass. Sapphire was supposed to be included on the iPhone 6, which was why Apple wanted so many furnaces and so much Sapphire. Over the course of negotiating with Apple, GT Advanced says the terms of the deal changed. I'll let GT's bankruptcy filing detail the gritty details for you: In hindsight, it is unclear whether Apple ever intended to purchase any sapphire furnaces from GTAT.
