The OP said:-
"My problem is that my provider can't deliver Nano-SIMs.
He mean it is possible at January 2013."
So problem for OP is using his (cut down) micro SIM right now.
I am in this same situation, the "official" Apple partner cannot say when the SIMs will be available even though the phone is released 21st Sept! They refer to some vague dates "around October".
If your carrier is a supported carrier, believe me, they will have NanoSIM's for phone sold by them or by Apple specifically for them on release day. What they may not have is a surplus of SIMs to give to people who purchased an iPhone 5 elsewhere.
The material the tray is made of doesn't matter as you can NOT cut a MicroSIM down to work in the NanoSIM slot. The NanoSIM is thinner as well as smaller. You would have to sand it down, which will most likely destroy the electronics in it.
You don't will unterstand it or?
The Nano-SIM is the same SIM like Micro or Mini.
They changed only the size and made this a little bit thinner (0,09mm for example a hair is 0,05-0,07mm).
I've adapt the micro to the complete Nano specs.
So the card is working in my iPhone 4.
The only questions what i now have is which material has the SIM Tray?
Is there a isolation?
Could i have problems with short circuits.
Yes i know that a lot of providers have nano-sims.
But not my provider and he can deliver at January 2013.
And no i can't change my provider i have a 2 years contract.
The "Micro SIM" is too thick to fit in the iPhone 5.
But the difference in thickness, even just 0.09mm, may cause problems when a cut-down micro-SIM is inserted into an aperture designed for a nano-SIM.
I knop that 0.09 mm is not a large difference in thickness, but will add up to be too thick if you try "jamming" one in the iPhone 5.

I have a feeling that when you get your iPhone 5 and "try" to put the "butchered" chip in your phone,
you will be coming back here saying that it is jammed / stuck and you have damaged the phone and need help, and will the warranty cover this ?
I'll save you the hassle. No, the warranty on Apple products does not cover stupidity.
The SIM has the Nano-Specs
Only the chip is a little bit bigger and has no plastic stripe.
You are contradicting yourself. If the chip is bigger and has no plastic surround, then it has not got the same specs as a NanoSIM has it?
You may have butchered it to the same physical size, but that does not mean it will work.
Guess you'll find out when your iPhone 5 arrives.
