Where can you find an auto-stereoscopic 3D cellphone launching for less than $100 (Rs. 4,299) sans contract? India, of course (by the way, "auto-stereoscopic" is a fancy way of describing a 3D display that doesn't require stereoscopic goggles). Budget mobile phone manufacturer Spice Mobility has announced the M-67 3D phone, which features a 2.36-inch 240x320 pixel display with a dedicated 3D shortcut key that lets users switch between 2D and 3D viewing modes for the UI, images, and video.
Unfortunately, the company doesn't mention the exact kind of auto-stereoscopic technology employed in the LCD screen. Almost all the technologies have limited viewing angles, though this is not exactly a big issue when it comes to cell phones.

The dual-SIM phone (GSM+GSM) is only equipped with a 2D camera, so you can view 3D but you can't capture it. Nevertheless, as we've seen from Nintendo, it looks like we'll be seeing 3D outside of theatres, TV sets, and computer monitors; 3D is going mobile. The phone in question also includes a 2MP camera, FM radio, 3.5 mm audio jack, and storage that is expandable up to 16GB. The handset will be sold through 50,000 retail outlets, including 750 Spice HotSpot stores.
