This specific one was addressed to the rom developers and differences in rom. I've kind of pin down the most probable cause to being something different in the rom.... could be something as simple as just a reg setting or possibly a missing file
I understand yr concern. Won't be making anymore new thread on this myself. But I aint giving up finding my answer....
Sprint and HTC can't win on this.....
I am just extremely real surprised that no one has checked on this issue before considering it seems to have been going on since the first 6.1 rom back in late 09.... Even with a minority of people using wmodem, I 've expected this issue to have been raised and resolved or at least find a thread somewhere where someone has at least tried real hard to get it resolved.
