As you have not specified in particular what is the unlock code required for you, i am giving the ways to unlock all the codes

NETWORK UNLOCK CODE:

You can unlock it by flashing your mobile if your mobile is a CDMA mobile...
The procedure for flashing your mobile is in the link below
http://hubpages.com/hub/How-to-Flash-your-cell-phone
It has an video explanation.

If your mobile is not an CDMA mobile , you can get the network unlock code(NUC) by just contacting the current network provider customer care department.It is free of cost.

The restriction code can be got from your old service provider..This restriction code is kept to prevent someone who stole the mobile from using it with another provider...

They will have a security check done with your date of birth etc..to verify whether you are the exact owner of the phone..

After that they will provide you the restriction code to unlock it and use it with another service provider..

Do not pay anyone for this seeing some advertisement over internet . That is all fake ads.

The above procedure works and you can verify that by seeing the rating of an happy customer here..

If you try pin more than few predefined no of times your phone will ask PUK code which can also be given only by your service provider which is specific for each and every mobile number . Do not try PUK(new pin code) code many times or else your sim will be blocked and you will need a new sim.

SECURITY CODE:

If you are talking about the security lock code to enter into the phone then once it is lost nothing can be done except flashing the mobile . Because if anybody can give the security code created then who ever who steals your phone can get into it and get your valuable information.

So as safety precaution to avoid that they have designed it such that if you forget the security lock you have to reset the mobile memory by flashing the mobile at an authorized service center.So while flashing the mobile all the data in the mobile memory will be lost and you can again start using the mobile.

Trick 1. Anonymous Browsing

Use free Proxy Server which allows you to browse the web anonymously and access sites that are blocked. Here is the list of few proxy servers which I came across while Googling..

http://www.browserjump.com/
http://www.ninjaproxy.com/
http://www.kproxy.com/
http://proxify.com/

Trick 2. Google Translation

In case if your organization has blocked all the anonymous proxy servers, you can use Google Translator( also called as Google Language Tools) service as your proxy server. Google Translator translate pages from one language to another language. You can surf the blocked web pages by translating them from English to English(or any language which you desire).

Replace WEBSITE with your favorite site address in the following URL and start accessing them

http://www.google.com/translate?langpair=en'en&u=WEBSITE
Example: http://www.google.com/translate?langpair=en'en&u=http://mgopinath.blogspot.com



Trick 3. Google Mobile Search

Google Mobile search service translates HTML pages to mobile phone browser compatible by removing style sheets and java script. You can use this service to browse the web pages in text only format.

Replace WEBSITE with your favorite site address in the following URL to start accessing them

http://www.google.com/gwt/n?u=WEBSITE
Example: http://www.google.com/gwt/n?u=mgopinath.blogspot.com
