Japanese mobile tech blog Blog of Mobile has uncovered what seems to be two variants of new Sony Ericsson Android devices. The two phones, codenamed MT11a and MT11i, were discovered by digging through User Agent Profile specifications on the Sony Ericsson site.

The two Android phones will reportedly run Android 2.3 Gingerbread on top of a single-core ARM Cortex A8 processor, which can run at clock speeds in the range of 600 MHz to more than 1.0 GHz.

The Sony Ericsson devices will sport FWVGA (854×480) touchscreens, with virtual keyboards, as the User Agent Profile specifications don’t seem to indicate the presence of a physical QWERTY keyboard. Support for Bluetooth 2.1+EDR also seems to be indicated.

The phones will also be medium-sized, as Sony Ericsson reportedly uses handset model names beginning with “MT” for its medium-sized devices.

The devices seem to be variants of each other, and speculation based on the models’ codenames is that one may be intended for global release (MT11i) and the other for the United States (MT11a).

Sony Ericsson has been adding more devices to its line of Android devices, with two new ones (the Xperia ray and Xperia active) in addition to the Xperia play, arc, pro, and neo.

Very little is known about the recently uncovered Sony Ericsson devices for now, but we’ll surely bring updates about them as soon as they arrive.
