I brought my Motorola Droid Pro back from the USA to Switzerland. It has never been actively on any network, as i bought it through Amazon as a "spare phone" on a Verizon network. I never activated the verizon chip. I am now back in Switzerland and when I try and put in my Swiss SIM card and access the network, it asks me for "SIM network unlock PIN". Does anyone know how to unlock it? thanks.
