Viewsonic's ViewPhone 4s was on hand at Mobile World Congress and we couldn't help but stop and check out this surprisingly likeable handset. First off, the 326ppi 3.5-inch IPS display is beautiful, very beautiful. Other notables include dual SIM support, a 5-megapixel camera, a front-facing cam and four gigs of storage that can be augmented via an SD card. The housing wasn't complete in the handset being shown, though the design is pretty sharp with the inclusion of a trapdoor on the bottom which folds open to reveal a SIM tray and the slot for expansion memory. The interaction with the Android 4.0 OS was really fast and perfectly smooth with the standout being the ViewScene 3D launcher interface. Have a look at the video for a quick once-over and the gallery for pics from every angle.
