For those of you living in Latin America, here you are the Radio Baseband for Movistar. Just install the SBF or Nandroid of your choice and then install the baseband from OR and voila!
I have been using the VIVO SBF and it`s running fine. Only problem is that i can`t connect to my exchange account, but at the moment i don`t know if is the milestone or the exchange server.
