It will be interesting to see future iPhones essentially made out of glass. Even now iPhone fans and Apple enthusiasts are excited about the type of material iPhone is made from. Though there have been expressed severe environmental concerns regarding the kind of material from which an iPhone is manufactured and how it is discarded once done with.

Recently, Apple has reportedly filed a patent application for a handheld device that has a case made of only glass. The material is said to be radio transparent and it could be made water resistant too. The past where iPhone 4 and iPhone 4S lag behind this new cased iPhone is that they have two pieces of glass, but it is inside a steel frame.

Surely, having a glass case is something that is one of the many features Apple would want to market its next product with and who knows, may be like, Siri, which has already received a lot of claim against its advertised performance, the glass-made iPhone might well not have anything other than that physical feature.

However, there is another thing should goes against it, which is its delicacy. Though glasses used in machines and technology equipments are strong, but having a hard fall is something which would be enough to shatter it into pieces. Further details have not been confirmed as to what Apple’s vision is with a wireless communication device made entirely of glass. It might have a specific use for some companies and industries and may not be available for general public. But it is too early to say.
