KT, an exclusive local partner of Apple to sell iPhone, plans to introduce a new version of iPhone, which is iPhone 4G to its customers by April 2010, sources say.

Executives of the company states that:

“We don’t see any bigger hurdle to introduce 4G iPhones here, as legal issues were completely cleared. It’s possible to launch the devices within the first half,” a high-ranking KT executive told The Korea Times, asking not to be identified.

“Still, there are some 3G iPhone stocks. But KT and Apple have reached a broad consensus to introduce the advanced models as early as possible,” according to the executive.

The new iPhone is rumored to have a larger OLED screen, a 5 Megapixel camera (dual maybe). removable battery with improved life, better wifi support, titanium body, 64GB and 128GB versions, dedicated graphics processor and a dual-core processor for smooth user experience. On top of that, a new firmware, 4.0 is rumored to be released this month, at Apple’s WWDC.

If these rumors are true, then this new iPhone will be miles ahead in terms of hardware than the NexusOne. Though the current comparison between the two devices shows that Nexus One has the lead in terms of onboard hardware, but with a dual-core processor, dedicated graphics hardware and dual 5MP camera, iPhone 4G would be at the top of the notch.
