Number one, only GSM network phones can be un-locked so that the phone can be swiched to another network. The acual turm is sim-locked, meaning that the phone wont take a sim card from a difrent company. GSM companys Include Cingular, T-Mobil, and a host of other smaller and inernational companies.
Number Two. Each phone has a diferant number to unlock it. Not just each phone modle, each individual phone. The number to unluck it is baced on its indivdual identification number or IMEI number. Company workers will not be able to give you the number, they have no way to get it. The only way to get the number is to use a GSM phone un-locking program.
Three, and fianly, the programs that will unlock a phone are not readily avalible. Only the manufaturers normaly have them, however some hakers and programers have desinged programs that will do this. They can be found on the indernet. Normaly a fee is invalved to unlock the phone this way. Also remember that not all phones are sold locked and may acount for some that are out there unlocked.
