Right now the thinnest smartphone in the world is a model made by NEC, if I’m not mistaking, but the iPhone 5 concept below takes away the crown, thanks to its slim waistline. This model, made by Alternative Industries measures a mere 4mm in thickness and it looks impressive.
The handset incorporates an edge to edge screen, that actually eliminates the upper and lower edges as well. This iPhone concept integrates the SIM into the device and I’m guessing that we’re dealing with a 4 inch smartphone here, but it’s only speculation right now. With a waistline so thin, should we fear that this phone can break easily?
