 Bizfriend, not all basebands are unlockable (i should say software unlockable ) so check if yours is unlockable here

If your baseband is unlockabe just search a tutorial on iclarified to go through the steps.
 
If not and/or if you want to or have to Unlock with gevey SIM as americane suggested buy one on ebay or craigslist ($25-50) !!
