This is some interesting stuff. With a March 7th (or February 29th) announcement date in the pipeline for the iPad 3, the Wall Street Journal has used the venerable “people familiar with the matter” to state that the iPad 3 will receive AT&T and Verizon 4G LTE networking, and when 4G is not around, will downgrade to an older networking technology (i.e. HSPA+. 3G or 2G). Other purported specs include a 2048×1536 Retina display, a quad-core Apple A6 system-on-a-chip (we think it will be a dual-core), and an updated form of iOS.
