My Palm Centro died, and I purchased a Palm680P. No problems. But I needed to unlock my wife's Centro, and it has been a nightmare. She first took the phone to the local AT&T store where we bought the phones. They said they can't unlock phones, and said to call customer support, which I did. The support technician gave me the unlock code based on the phone number. I tried it, and the phone gave the message that it had been successfully unlocked. But when I then installed a T-Mobile SIM card I bought, the phone gave an error message that the SIM card could not be used. (That same SIM card works fine in my Palm 680P). I then called customer support again, and this time gave them the IMEI number from the Centro. They then gave me a different code. Same result. I then took the phone back to the AT&T store, where the technician tried several times with no success. He got yet a third unlock code when he called tech support. Finally, he said he had done everything he could do. I then called tech support again, and they told me that the phone was now probably locked to AT&T forever, because more than 5 attempts had probably been made.
I think they have now lost me as a forty year customer, but I am still wondering if what they told me is true. Is the phone now locked forever to AT&T? That just doesn't make any sense to me technically.
