The Sony Ericsson MT11i has been discovered hidden deep in Sony Ericsson's website in the form of a UAProf (user agent profile) by IT168. As always with UAProfs, there isn't really that much information, other than proving that this device exists (or is planned). What we do know for sure is that its touchscreen will have a resolution of 854×480, which isn't really all that surprising, since that's the standard resolution that Sony Ericsson uses for its Android-powered smartphones.
The MT11i will not have a physical keyboard of any sort. That's obvious from the lack of a ‘K' in the name, but also because the UAProf lists ‘phone keypad' as the input method available in this phone. The processor will be a Cortex A8 affair, probably yet another single-core. So for now, the only dual-core Sony Ericsson smartphone that we've heard of remains the aptly named Xperia Duo.
