I upgraded an 8700c that I had previously unlocked. The upgrade installed fine, but now it seems that it has re-locked to AT&T (note I did remove the vendor.xml file). I don't have my unlock code handy, but I'll try it if I can find it. Has anyone else experienced this? When I insert my T-Mobile SIM, I get an "Initialization Failed" message. I've tried taking the battery and SIM out and restarting.
Note I had my T-Mobile SIM in the BB for the entire process.
