Have been contract free for the past 3 years now, so will again be buying the iPhone 5 unlocked direct from the apple store
Am currently with giffgaff, which runs on O2's network, so no chance of 4g anytime soon, but not too fussed about that for the moment
I would rather a cheap unlimited 3g+ data plan, then even a reasonably priced 4g with usage caps
I remember how much of a rip off 3mobile was when it was 1st launched (walled garden anybody? wow)
I got £400 for my 32gb 4s a couple of weeks ago which is a very decent return, and the reason why I dont mind paying the large sum upfront for the new devices
-- Now to the nano sim dilemma --
Last time I went to the apple store, the rep explained to me that when you buy the iPhone they will also transfer your standard sim to a micro-sim, free of charge, and it is an instant process.
As long as its one the main networks sims, they can do this. I can almost guarantee that they will offer the same service for transferring to the iPhone 5's new nano sims on day of release.
giffgaff is not a one of the main networks, so Apples sim transfer process would not be available for giffgaff users.
There is much discussions on the giffgaff forums about transferring to the nanosim, and it has been discovered that most sims can be cut down manually to the nano sim size safely.
There are 3 generations of sim cards(standard, mini, & micro) if you have the old standard 1st generation of sim card, then this will NOT be able to be cut down to a nano sim. But the rest can. Most people now do have either a mini or micro sim version.
iPhone ZenVideo have a video showing you which sims are compatible, and how to cut it down. They also have a template you can print off, in order to help you accomplish this

This will also apply to you if you use any of the other smaller networks, e.g Virgin Mobile, as they may not have nano sims ready to roll out straight away
Update - Just seen a tweet from 3 mobile stating they are offering nano-sims from today
--Pre-ordering the iPhone on Friday --
I probably wont have access to a pc/laptop on Friday morning in order to order via a web browser, so I checked the apple store app, which has stated you can pre-order the iPhone from the app on the day. Im not sure which will be the most reliable way to order! Hopefully apple can handle all the traffic and it will be a smooth process (fingers crossed)
--Which colour --
Ive bought the white iPhone for the past 3 years, but this year I feel im going back to black.
The black version just looks so sleek and beautiful, as unlike before the device is all black
Also with the black bars being used on the iPhone 5s screen for non 4inch apps, I feel the black iPhone hides these, as shown in apples presentation, whereas the white iPhone would highlight this.
