Unlock Nokia 6610 GPRS Data Side

I recently had my T-Mobile Nokia 6610 phone unlocked for the phone side but I am still unable to unlock the GPRS data side on the phone. I read the forum earlier and one of the facilitators said the GPRS data side can be unlocked, too. I am a current AT&T Wireless subscriber in the US and would appreciate any help that anyone can provide for me. I do have a current GSM phone and can find the IP address from that handset, but I just need the unlock code for data. This forum site has been very helpful and I appreciate all the help I have received. Here is the phone information:

Phone: Nokia 6610
Provider: T-Mobile
Country: USA
IMEI: 351540000631820

you will have to flash your fone with a clean Gprs setting
caus T Mobile has it locked that way and code cant unlock it
sorry i cant help you more
