I believe I have the answer...
If the phone is an unlocked phone that is originally set up to work on another carrier, it will have firmware that is pertanent to the orignal carrier. Each of the carriers have specific parts of the system software that may be updated from time to time.
In you case if I stand correct, the phone is looking for a specific carrier system software update. Being on a different carrier, it will not be able to properly download that software, and do the update.
This information is from some other technical discussions that I've read some time ago.
