Is it worth ordering the Xperia X dual Sim variant i.e. F5122? My understanding is that the current image for F5121 can be used for the dual sim variant?
If yes, is the functionality identical, apart from recognising one sim, and only 32GB of storage space. Is the SD card slot functional?
Also, do we have to buy a separate license for the F5122 image when it comes available, or upgrade an existing F5121?
