The 128-gigabyte Wi-Fi-only iPad will cost $799, while a cellular version pushes close to four figures at $929. The new iPads will be available on Feb. 5.
Verizon Wireless, AT&T, and Sprint Nextel both confirmed they would carry the higher capacity iPad.
The updated iPad represents a minor update to a device that already got a slight overhaul late last year. Many expect Apple to unveil a new iPad with more significant changes in the coming months.
The 128GB iPad has all of the same features as before, including a 9.7-inch Retina Display, a FaceTime HD camera, and an A6X processor.
Apple is hoping the higher-capacity iPad will be better suited for the business world. Over the past few years, the company has made a concerted push to get into companies for professional use.
The press release pointed out the potential appeal of the higher storage volume to businesses that traffic in data-intensive materials such as 3D CAD files, X-rays, film edits, music tracks, and project blueprints.
While Apple's share in the tablet market remains dominant, the company is starting to see increasing competition from lower-priced devices such as Amazon's Kindle Fire HD and Google's Nexus 7 tablets. In response, the company late last year unveiled the iPad Mini.
Update at 9:04 a.m., 9:35 a.m., and 12:25 p.m. PT: Sprint and Verizon confirmed that it will be offering the 128GB iPad.
