T630 Network Unlock code ?

[Coppull Buster]

Hi Guys

Please dont flame me for this one LOL
Ive been a loyal devotee of satpimps & now satpimps for years on the satelite scene but Mobile phone unlocking isnt my thing..

Ive just upgradeded my phone and I was hoping to give my old T630 Sony Ericsson to my daughter, but unfortunately the phone is network locked to vodafone and her sim card is O2. When I put her sim card in, it says wrong sim card inserted.

I have found lots of information on unlocking this phone, for example

if I press *#06# it tells me what my IMEI number is

if I press <**< then it says personalized with MNC2 and then shows Network (and a padlock symbol) which apparently means it is locked on that network

But if I press select then is says Unlock(Net)5 NCK:
and I have the option to enter the unlock code..

I know my IMEI number, how do I calculate the unlock code? there are plenty of online services offering to do it for a fee.. So Im thinking that there must be a program or calculator available that calculates the code!

Any help or advice would be greatly appreciated..

Regards
Buster

Just to follow up my earlier post...

I can confirm that my Old Sony Ericsson T630 is now unlocked

No wires, no special leads, clips or gizmo's..

After scouring the internet for a NCK unlock code calculator to no avail, in the end I rang Vodafone, gave them my IMEI number and asked for the network unlock code.. They were very helpfull and gave me the code for free, I couldnt believe how easy it was..

I simply followed the instructions, keyed in the unlock code and hey presto !

The phone is now working fine with an O2 sim inserted..
