1. It's Symbian thing. It can be scaled like we have already seen with old 3rd edition phones, but it doesn't seem to be problem free. Will change in S^4. 2. It seems to be 680mhz that would mean it's OMAP36xx and it's good to remember that TI OMAP3 will beat Snapdragons *** in GPU fight. OMAP3 will also be much more flexible than what Qualcomms Snapdragon is like we have already seen with N900, Droid and Pre. 3. It seems so. Nokia and T-Mobile USA have had some loving going on so it might be true.
Yes it does. In fact if you read more closely you'll see that it is the first mobile phone supporting every single 3g band available in the world. By the way these specs are for the chinese version of the phone. EDIT: It could be that those bands stated in the spec sheet can be for different models. Who knows.
