Nokia N75 firmware update

You need to have ATT unlock your phone and install Nokia's PC Suite. The PC Suite will walk you through the firmware update.

bought my nokia N75 through AT&T plan. i am trying to figure out how to update my symbian firmware.... i discovered that Nokia is not supporting a firmware update through AT&T. I feel like i am running around in circles when it should be easy to update software,,, thanks

:con?I have followed all the instructions to debrand mine (unlocked yet!)

I changed the product code in NSS to 0541358. Mine was originally 0545060.

Maybe mine is a newer version, not sure. I closed NSS, restarted the computer and the phone, opened NSS to check and the product code was still 0541358.

Yet, when I run the Nokia Software Updater it recognizes my phone just like the in the screenshot above but it shows my firmware version as being 20.1.172!!! This version is newest and branded one. Can I downgrade to the unbranded version (i think it's 10.2.055)?

Thanks!
