iPhone 4G to Have Glass / Ceramic Back and Removable Battery

John Gruber has posted that “Multiple sources familiar with the next iPhone have confirmed to me that the back is made out of some sort of fancy glass – and looks pretty much exactly like what’s pictured at Engadget.” He further points to an Apple patent for high-durability ceramic enclosures made using Zirconia that have glass like appearance and feel but are far stronger and more scratch resistant, and highly radio transparent for better cellphone reception.

Also, MacRumors points out that next gen iPhone might have user removable battery. The website says “image (above) shows break points in the casing that suggest the side compartment might be removable to allow the user to replace the battery.”

Our sources say that Apple will follow the same design principle when it comes to battery placement. Apple will fit bigger battery by removing the battery replacing mechanism and creating more space.  Like they have done on current iPhone and MacBooks.
