My little brother, since a few days, has been asking for a smart phone as he is entering into college. I consulted with some of my seniors and came to the conclusion that Apple is going to launch its another marvelous device .i.e. iPhone 4g. Currently Iâm using iPhone 4 and Iâm happy with its features, latest applications, cameras, etc. Iâm just wondering if iPhone 4g has extra and additional applications and features. Will it be available on Orange network? What would be its cost? Can anybody tell me apple iphone 4g release date?
