One change will be internal; the new iPhone will not have a SIM card and will feature both a GSM and a CDMA radio allowing the same unit to be used for both AT&T and Verizon, and with 3-4 antennas, it will be a world phone. In addition, the new version of the iPhone will sport an 8MP camera in the back and be powered by an ARM Cortex A9 processor, using a Qualcomm chipset. The report says that it is not yet known if the processor will be single-core or dual-core.
The next major update to the Apple iPhone, according to the story, will be the iPhone 6 which will launch in the Spring of 2012. That dove tails with an earlier story that we reported, hinting at a Apple iPhone 6 to be launched next Spring, equipped with low-temperature poly-silicon LCD displays made by Sharp, for a thinner and lighter design.
