Rumors that Apple’s third-generation iPad tablet would include 4G LTE connectivity have persisted for almost a year, and now the news is all but confirmed. Less than an hour ahead of Apple’s press conference in San Francisco, a source speaking with 9to5Mac confirmed that Apple’s inventory system is now being populated with entries for an International version of Apple’s next iPad equipped with integrated 4G. “MD369LL/A – IPAD WI-FI 4G 16GBLACK – USA.” is one such entry. Apple’s iPad 3/iPad HD unveiling is scheduled to begin at 1:00 p.m. Eastern, 10:00 a.m. Pacific and BGR will be reporting all the news as it breaks.
