As promised at Tuesday's announcement, Apple has opened up pre-orders for the iPad mini and fourth-generation iPad today. Anyone interested in Cupertino’s latest tablets will be able to place an order via Apple’s website or the iOS Store app. The iPad mini will be available in 34 countries at launch, including the US, UK, Canada, France, Germany, Hong Kong, Japan, Australia, and New Zealand. The 16GB, 32GB, and 64GB Wi-Fi models cost $329, $429, and $529, respectively, with delivery expected on November 2nd. The Cellular models, meanwhile, command a $130 premium, and won't begin shipping until "mid-November."

Those not enthralled with the iPad mini may be more interested in the fourth-generation iPad, also available for pre-order starting today. Apple has tweaked its flagship tablet to include its new A6X processor, global LTE support, a front-facing FaceTime HD camera, and a Lightning port. The starting price remains the same at $499, and like the iPad mini, delivery for the Wi-Fi models is due for November 2nd. As always, you'll need to be quick if you want to ensure delivery of Apple's latest devices on launch day.

Update 1: It looks like the initial batch of the white Wi-Fi iPad minis have been snapped up in the US, with each storage size now showing a shipping time of two weeks. The black and slate variant seems to be unaffected so far.

Update 2: As 9to5Mac points out, the black variant of the 16GB Wi-Fi iPad mini is now showing an estimated shipping time of two weeks as well. The 32GB and 64GB versions, meanwhile, both still list the original November 2nd ship date, while the LTE versions are slated for mid-November.
