Carrier AT&T informed 9to5Google.com that they will be bringing the LG Thrill 3D to their network “in the coming weeks”, priced at just $99. The handset is also referred to in AT&T’s press release as LG Thrill 4G. That’s a really competitive price and LG Thrill is a pretty amazing phone. It features a glasses-free 3D display, a 1GHz dual-core processor with dual-channel RAM and five-megapixel stereoscopic cameras for capturing 3D footage in 720p and stills, among other things. The device will run Gingerbread out of the box and AT&T confirmed in a separate statement this morning that they will be updating all post-paid Android smartphones released in 2011 to Gingerbread, including Motorola’s Atrix 4G that received an update this morning, HTC’s Inspired 4G which is due to get it “in the coming weeks” and four other phones.
