This is an interesting report, I’d say. Apple is said to be getting the curved glass surface for the next generation iPhone 5.

Cover glass makers are reluctant to commit investment to the purchase of glass cutting equipment due to the high capital involved, said the sources.
According to some legit sources, Apple has purchased 200-300 glass cutting machines to be used by glass makers, as reported by DigiTimes.
There has been no timetable yet for the volume production of iPhone 5 as Apple is currently still working with related suppliers including those involved in cover glass, glass cutting, lamination and touch sensors to improve yield rates, the sources commented.
The report contradicts with an earlier theory which claims that the fifth generation iPhone could adopt iPhone 4 like design. But why Apple is making the glass surface curvy? Is it for comfort or making the glass resistant to break? Our educated guess is that Apple is looking for an alternative after receiving number of complaints from user.
We already know by now, that iPhone 5 will carry metal back, A5 processor, larger display,thinner bezel (edge-to-edge screen), dual mode, 8MP camera. As always, we will bring you latest updates on Apple iPhone 5. Just follow us on Twitter and become a Facebook fan.
