From 8.01am this morning, the Apple UK online store started taking advanced orders for the iPhone 5, which features a larger 4-inch screen, improved camera technology, faster A6 processor, LTE, iOS 6 and a new dock connector.
Available in Black & Slate or White & Silver colour options, the SIM-free phone costs £529 for the 16GB model, £599 for the 32GB and £699 for the 64GB.
Consumers are also able to register for the device on a range of contract options with Three, Vodafone, O2 and EE, the new network that includes Orange and T-Mobile, along with the UK's first 4G LTE service.
EE will be the only network to be able to offer the iPhone 5 on 4G, enabling its customers to access mobile internet speeds around five times faster than current 3G. More details are to be announced on availability soon.
Apple said at the press conference that typical US prices on a two-year plan would be $199 for 16GB, $299 for 32GB and $399 for 64GB.
Vodafone has just announced its iPhone 5 pricing on 24-month plans. The 16GB model will cost £249, £99 and £49 respectively on the 100 Plan (£25 per month), Vodafone Red (£37 per month), and Vodafone Red (£42) tariffs. It will be free on the new premium Red Data plan.
The 32GB will cost £349, £209, £149 and £89 on the four respective price plans, while the 64GB will cost £409, £289, £229 and £169 respectively.
Following an Apple announcement at the product launch, Vodafone has also said that the 16GB iPhone 4S price will be cut to £139 on the 100 Plan, £19 on the £37 Vodafone Red tariff. It will be free on the Vodafone Red £42 plan and the Red Data tariff.
All experts expect Apple's online pre-order stock to sell out quickly ahead of the phone's on-sale date of September 21, when it will be available to buy in stores.
As with previous Apple product launches, long queues are expected at Apple Stores on that day as fans line up to get their hands on the smartphone, which features Apple's biggest redesign since the iPhone 4 in 2010.
