Microsoft Windows Phone division head Andy Lees revealed dual-core LTE Windows Phones are coming:
Microsoft's head of its Windows Phone division, Andy Lees, says that future smartphones that run the mobile operating system will have support for dual-core processors as well as the faster LTE wireless networks. In a chat with AllThingsD.com, Lees says that Microsoft wanted to wait until its software could better handle more than one mobile processor core. However, Lees claims that as far as the current Windows Phone 7 devices, "They’re all single core, but I suspect that they will be faster in usage than any dual-core phone that you put against it, and that’s the point."
As far as LTE support, Lees says that Microsoft wants to make sure that any Windows Phone 7 products don't have issues with battery life with any LTE technology. He says, "The first LTE phones were big and big (users) of the battery, and I think it’s possible to do it in a way that is far more efficient, and that’s what we will be doing."
