Greetings. my verizon droid bionic xt875 uses not open to operate with another provider. I wanted to, but no peer when it does in the network. I wonder if there are any alternatives for me to work with gsm phone with another carrier other than Verizon. If not to unlock the bootlouder can do what I want. let me know. sorry I'm using google translator jejejejeje The phone is designed so that the FDN does not allow calls with the sim that you've put in, try another sim and sige alike. I have already put the rom eclipse.
