Blu Products has announced the Vivo 4.3, a new smartphone with a 4.3-inch WVGA Super AMOLED Plus display (likely sourced from Samsung's Galaxy S II parts bin) and dual SIM capabilities. The Vivo 4.3 runs Android 4.0 on a 1GHz dual-core processor and has an 8-megapixel camera, 4GB of internal memory, and microSD support. It's unusual to see dual SIM support in a phone with such decent specs — even if there's no 4G — and even more unusual to see a device like this in the US market for a reasonably low price. The phone will be available unlocked in the US in September for $249.99, and Blu Products plans to release the device in the Latin American and Asian markets shortly after.
