Subsidy unlocking and de-branding are not the same. If you have had your account with AT&T / Cingular for more than 90 days, you can call customer service and request the subsidy unlock code for free. And no, you don't need some special program or cable to unlock. There is no unlock code "in" your phone. The "code" is actually nothing more than a mathematical equation that is programmed into the rom of every cell phone. It converts your IMEI to a "code". It is not stored "in" your phone. When you insert an "invalid" smart chip, the phone loads a snippet of code from the ROM. It runs an equation on the phones IMEI and compares it to an inserted solution (your code). No, you can not flash over this code, no you can not modify this code, no you cannot "hack" this code. Just wait 90 days, or find a service online. There are several that will provide this service for a minimal fee (around $20.00 USD). If you purchased a pre-paid phone, if it is not already unlocked, just call customer service, they will give you the unlock code immediately. Just make sure you request the SUBSIDY unlock code, not the PUK unlock code. It will be e-mailed to you within 24 - 72 hours. If they give you a code immediately, it is probably the PUK unlock code. Do not try this code. You only get three attempts before your phone is permanently locked to Cingular / AT&T. Tell the representative...
