Still holding out for a larger iPad? Well, you're certainly not alone. Thanks to new details from 9to5Mac, it looks like Apple's prepping for a reveal as well. The site has a solid track record when it comes to rumors, and it reports that both hardware and software tweaks are in the works for the 12.9-inch slate. Two models, code-named J98 and J99, are reportedly in the testing phase alongside tweaks to Apple's mobile OS to outfit the extra screen real estate. As you might expect, the difference between the two is one is WiFi-only and the other carries both WiFi and cellular connectivity. Among the changes to iOS is a split-screen feature that could be announced for current iPad models as early as WWDC in a few weeks.
