The iPad Generation 3 was significantly more powerful than the two previous iPad models and introduced the “Retina” display, a 9.7-inch multitouch screen at 2048×1536 (264 ppi). Internally it used a dual-core 1 GHz Apple A5X processor with quad core graphics; 1 GB of RAM; 16, 32, or 64 GB of storage; a rear-mounted 5 megapixel iSight camera (1080p); a front-mounted FaceTime camera; 802.11n Wi-Fi, and Bluetooth 4.0.
This specific iPad model supported 4G LTE connectivity on Verizon’s network in the US.
According to Cult of Mac, the iPad Generation 3 had the “shortest lifespan of any iPad in history. Apple debuted the fourth-gen model just 221 days after the iPad 3 went on sale. The iPad 4 added the Lightning connector, making the iPad 3 the last iPad to support the old 30-pin dock connector.”
The Smart Case for was made of polyurethane and fit several iPad models including iPad 2 (2nd generation), iPad (3rd generation), and iPad with retina display. The Smart Case offered full protection and the cover was magnetic so when the case was open the iPad woke up and automatically went to sleep when closed.
The interior of the case was made of a soft, color-matched microfiber lining that helped keep the display clean. By folding the cover into a triangle, Apple advertised the case positions as a “FaceTime and movie stand” while upright and a keyboard stand to “tilt iPad into a comfortable typing position” when flat.
