To unlock it you need to go through a process called "jailbreaking". This will allow you to install pirated software and use other GSM providers (Note: Verizon and Sprint do not use GSM).
Jailbreaking will void your warranty and significantly decrease the reliablity of your iPhone.
I highly recommend that you avoid jailbreaking at all costs.
