The much-anticipated 3G model of the iPhone, largely expected by many to be introduced in the Worldwide Developer’s conference to be held by Apple on 9th of July for this year, might be shipping out in July. Apple’s forthcoming 3G iPhone would in all probability incorporate a GPS module and would be slightly thicker than the current versions. A more rounded, stylish form and a glossy black back has been predicted as far as the visual appeal and details predictions go. An additional prediction has been the replacement of the recessed headphone jack with a jack flush. The first thing it has been said, which the people will inevitably notice is that the second generation iPhone will be about the same size and shape as the first one. But of course, it will have 3G and proper GPS. The physical characteristic that is going to stick out like a sore thumb among older models is the difference in the back of the phone. Instead of the normal metal backing that was used previously, Apple has now opted to give the iPhone a sleek black back making it look more sleek and sexy. Not to mention, the absence of metal to deal with has given us rounded corners instead of the not so awesome looking angular edges. The battery is still not removable. The thickness of the phone is said to be of slightly increased size than the first generation devices. The headphone jack which was highly inconvenient to users has finally been done away with and in its place is a flush fitted in the body itself. The device on the whole is more or less the same size and of same screen resolution as the first generation product. There have been no speculations as regards life of the battery and capacity of its storage. Though it has been pointed out that the sleek glossy black back could in all probability just be a casing, we never cease speculations do we? Especially when it comes to Apple and iPhones.
