The iPhone 6S and 6S Plus are now on sale, both in-store and online. Though you'll have to wait if you order online.
All four colours of 6S are listed as being dispatched in one to two weeks on the Apple online store. The situation is even worse for the iPhone 6S Plus – all four colours are listed as shipping in three to four weeks.
You might have more luck in store, but they're guaranteed to be busy today. Better sharpen your elbows to deal with the crowds.
If you can't wait until things calm down a bit, Apple usually lets you reserve an iPhone to buy in-store, but it's now stopped accepting them for today.
Reservations will re-open at 6am tomorrow morning, however.
The 6S starts at £539, and the 6S Plus at £619.
Both handsets have unique features that you won't find on any other phone. One of these is 3D Touch, a version of Force Touch on the Apple Watch, but with the ability to register three levels of pressure instead of two.
Tap and hold an email in your inbox, for example, and you'll peek into it to see what it's about. Press harder, and you'll pop it open so you can perform the full range of actions like forward or reply.
Apple's new efforts also offer the so-called Live Photos feature, which adds a second and a half of animation to your photos either side of when you pressed the shutter.
It brings them to life, but also takes up more space than a standard photo.
