As it says, I can unlock most new Nokia's so you can swap networks. Totally Free.
All I need to know is your IMEI number and what network you are on.
Will do the rest for you and give you the code to type in.

The IMEI number is a unique number for each and every PHONE (not SIM). It is how the phone is identified on the respective network - not the phone number, together with the SIM id number.
The SIM tells the phone what network to use
The phone contacts the nearest cell for that SIM (looks for cells with a specific code on the required frequency) & reports its IMEI. The network then knows that IMEI xxxx is connected & that with that SIM is equiv to tel number 07xxx
To lock a phone to a network, the phone is preset with an internal lock code. To unlock normally requires some sort of data connection, a PC & some software. I've recently unlocked an XDA from O2 & it needed software.
There are a couple of possible ways this could be done, but interested to hear how...

All Nokia DCT4 phones (roughly 8310 onwards) can be unlocked remotely. Originally you needed a piece of software and a dongle plugged into your parallell port to calculate the unlock codes. Now there are certain places offering this service for free as the market has been flooded and some places are offering it for free via websites, others are still charging £20 for it).
Once the code has been calculated you put a sim card into a phone that is not usually accepted i.e. O2 Sim in an Orange phone, and the phone will ask you to enter the unlock code, enter the code and away you go.
Most other manufacturers still need to be unlocked with a cable although I believe it is now possible to remotely unlock some motorolas using a similar technique.

Just to clarify something Puff has said...
The IMEI is not 100% unique to a phone - there are some duplicate IMEI's around (which are legitimate - I'm not including the ones that have been illegally changed)
The IMSI is the code that is contained within your SIM card (which is the number normally printed on the card itself).
When you use your telephone, both these numbers are transmitted to your mobile phone service provider.
Therefore, the IMSI combined with the IMEI makes a telephone truly unique on the mobile phone networks. I think this is what PTMW was trying to say.

What had been stated above about how this is done is correct, I can only do it on DCT4 phones.
Dazza - You would be a pain and have your phone on o2! I need a network code and yours isn't listed. Once i find it though I'll put up a code which you can try.
I did this yesterday on my 7250 and it works fine.
This is also how the networks like unlock phones too, Orange Charge around £30 if you want it unlocked at the end of your contract.

Thanks Burr
Much more sucinctly put than me after a few beers
That's how Location Based Services work that are being touted by the network. The Network servers knows what cell you are in so if either a) you wish to find nearest <insert advert paid for service here> then it locates the cell you're in and txts back the target address & b) is someone wants to know where you are, then they query the servers & it comes back with a geographical location for the cell you are in.
It is possible to use trigonometry on adjacent cells and signal strength to be reasonably accurate as to exact location.
Networks are gettin all excited 'cos they can charge 10p a hit for this stuff & its all produced as a byproduct of the information necessary to run the networks anyway.

u might have to change the second digit in the codes given
ie #pw+028803747660401+1#
would become
#pw+018803747660401+1#
u change it to the digit b4 the digit given
ie
1=0
2=1
3=2
4=3
and so on
9=0
