According to recent reports, Apple is believed to launch its next iPhone (referred to as the iPhone 5) at this year’s Worldwide Developer’s Conference (WWDC). Except for the iPhone 4S which was launched in October, the previous models (iPhone 3G, iPhone 3GS and iPhone 4) were all unveiled at the WWDC event.

A leaked calendar shows an entry for a “Corporate Meeting” between June 11 and June 15, which might very well indicate the time for WWDC. The report also claims that the next iPhone will utilize glass-to-glass (Glass/Glass, G/G) touchscreen technology probably supplied by TPK Holding and Wintek.

Glass-to-glass technology is superior to film-to-glass technology because they consist of a double layer of glass instead of a double layer of film and glass. The advantages of glass-to-glass technology mainly reside in the fact that these touch screens can be used in more extreme conditions.
