iOS 5 was confirmed by Apple to be announced on 6 June, when the 2003 annual Apple special developer is held. Steve Jobs will directly introduce this latest iOS, iCloud (latest Apple internet cloud services), and Mac OS X Lion.
Unfortunately it looks like there will be no new iPhone model announced at the event. Even so, according to rumors, new iPhone 4S will be released in July or August, while the iPhone 5 new will be present next year. iPhone 4S will integrate support two simcard GSM-CDMA as well as add 3-4 antenna in it so that there is no longer a problem signal as the launch of the first iPhone 4.
Not only that, the micro-SIM which is now used iPhone 4 might be more scaled down again for the next generation iPhone, of course it's quite troublesome because the user must have a special SIM card that could have just provided Apple through collaboration the operator.
Site of origin of Japan, Macotakara also indicates an increase in terms of the camera be 8MP and processor ARM Cortex A9 dual core. Both in terms of model doesn't seem to be any change, but it could just be iPhone 4 GB 8 GB version as it does on the iPhone 3GS 8 GB.
Whatever happens, the event WWDC will be held less than a week away, hoping only iPhone 4S announced there.
