The Street reporter Scott Morris says his sources from Cupertino revealed that Apple is actually more excited not for the next iPhone, which will bring small improvements, but the iPhone 6. Improvements in the fifth generation of the iPhone will most likely be dual-core processor A5, 8-megapixel camera, maybe aluminum rear panel and NFC chip and embedded SIM card, if the sources of Mr. Morris are right for interim upgrade.
According to the reporter from The Street, sixth generation will be quite interesting, because it should come in large 4-inch screen and 4G LTE support. Still no one guessed when the iPhone 6 will appear.
If the rumors that the iPhone 5 will be released in September, are true, it seems that Apple will run different versions of the iPhone in six months, presumably to keep up with competition on the green robot. The emergence of LTE version of the iPhone will most likely be synchronized with the launch of 4G networks of the largest U.S. operators, which must be taken at this time next year.
