We’ve already heard about the Sony Ericsson LT28at as the phone is believed to be an American AT&T variant of some sort of the LT26i (Nozomi). The LT28at is apparently codenamed Aoba and it might have received its Bluetooth Certification.
According to Blog of Mobile, the Sony Ericsson LT28at Aoba is the phone that is listed above under the rather strange name of “New eDream 6”. The design model number clearly states “TBD” which indicates that the manufacturer is trying to keep things under wrap at the moment. The software version (6.0.A.1.94) seems to be in line with what the next build numbers for the Xperia line should look like. The phone is expected to sport a dual-core processor clocking at 1.5GHz and a 720 x 1280 resolution HD screen.
