According to a report from CNET, Verizon, AT&T and T-Mobile are all seeing estimated ship dates slip to at least December, though Apple's own supply for Wi-Fi + Cellular iPad minis continues to improve.
The shortage suggests supplies are still constrained for the cellular 4G version of Apple's high-resolution 7.9-inch tablet, as Verizon recently pushed back shipping estimates to Dec. 2. Previously, the nation's largest carrier was quoting a target date of Nov. 25, but a spokesperson is now unable to say when the device will hit store shelves.
As for AT&T, the company's website says all models of the Retina iPad mini will ship in 21 to 28 business days. T-Mobile, too, is back-ordered for an estimated 6 to 8 weeks.
Although cell carriers may not be getting adequate supply of the hot-selling mini, Apple has been bolstering its stock for customers, who now have to wait 5 to 10 days for the unit to ship. This is a major improvement from launch day, when even the first orders showed wait times of a few days. At the time, Wi-Fi + Cellular models showed 5- to 10-day ship-by times, which later fell to weeks.
In a note to investors, KGI analyst Ming-Chi Kuo said Apple's manufacturers will reach mass production levels sufficient early next year, with shipments expected to grow 102 percent over the next quarter.
