Need Unlock Code for a ATT Treo 680.

[cax2]

I have T-Mobile service and just bought an ATT Treo 680 that is locked.  Does anyone have the unlock code for an ATT Treo 680?

I'm pretty sure that the unlock code purely depends on the Serial number of your Treo. You can check your Serial number IMEI by pressing *#06# Though I do not have any knowledge on how to unlock a Treo.

You can call your carrier (AT&T) and request the unlock code, or you can go to an unlocking service and purchase an unlock code.

Is there a free unlock code for Rogers Treo 680, anybody?  Thanks.

Can anybody know the unlock code for Treo 680 locked with At&t. I got the unlock instructions from http://www.mobileunlockguide.com/

The unlock code is tied to your IMEI, there isn't a generic unlock code. Just call AT&T and request the code.

I received my unlock code specific to my 680 IMEI code.  After successfully unlocking the phone, it's asking me for a new PIN. Then...it asks to verify new PIN.  After I do that, it says that I've entered the incorrect "Password". 
Any thoughs?
