As usual with Sony (or Sony Ericsson) smartphones, the final letter in the model number indicates that there will be two versions of the device, with two different radios. So the ST27i (‘i’ for International, presumably) will get HSPA support in the 900 and 2100 bands, and the ST27a (‘a’ for Americas, we assume) will come with the 850/1900 bands for 3G (or 4G, or whatever else you want to call it). Those are just the bands that AT&T uses for its non-LTE 4G (HSPA) network, so who knows, maybe this phone will be released by that particular carrier at some point. Don’t get your hopes up, though, for Sony may just decide to sell it unlocked in the US.
The Lotus will have a touchscreen with 480×854 resolution, an ST-Ericsson NovaThor U8500 1 GHz dual-core processor, and according to the user agent profiles, will run Android 2.3 Gingerbread when it launches. That would be rather disappointing, since we’re probably still quite far from this device’s release, yet Android 4.0 Ice Cream Sandwich is already more than half a year old.
However, Blog of Mobile speculates that the Lotus may in fact arrive in stores being powered by Ice Cream Sandwich, so we’ll have to wait and see how this pans out.
