Alongside its new iPad mini, Apple also introduced a fourth-generation iPad, building upon the success of the third-generation “New” iPad with a Lightning connector and slightly updated internals. As expected, all three capacities of the fourth-gen tablet sold out on launch day.

Today, however, all capacities are back in stock, meaning that Apple has caught up its production of the new 9.7-inch tablet to the demand that its customers have for it. Its US, Canada, Australia, Hong Kong, Japan, Korea, and Singapore online stores all show that the tablet is “In Stock,” and are available for purchase right now.

Meanwhile, UK, French, German, Danish, Norwegian, Swedish, Italian, Spanish, and Portuguese stores are unfortunately still showing “3-5 business days.”

The new, fourth-generation iPad adds better CPU and GPU performance and a Lightning connector, all while maintaining its svelte profile and 10-hour battery. At the moment, Apple’s only selling WiFi models, but LTE models are coming at some point this month.
