Nobody is willing to wait for a few more days to see the real iPhone 2.0. Everyday new rumors are pouring in with spy images of the upcoming device to reveal the new model before its official release date. Host Optical, a Taiwanese company, claiming to be Apple’s partner in developing the touchscreen display of its upcoming iPhone has revealed pictures of the new displays. The sizes of the displays show that Apple is on its way to shrink the size of the iPhone, developing a future generation nano perhaps. The 2.8-inch and 3.2-inch touchscreen versions are smaller than the current 3.5-inch screen size. Host Optical claims that these screens will be more durable, waterproof, heat and humidity resistant and the sensitivity of the touchscreens will not diminish over time. Whether this nano version will be the upcoming iPhone 2.0 or is it some future generation iPhone is however not clear.
