My go phone sim wasn't recognized by my skyrocket it said please insert proper usim, and etc, I called go phone customer service from a seperate line, anyways the service Rep said that the sim was locked to my prior go phone and I had to put it in my skyrocket and he had to change a few settings after first reboot I had phone and text, but no data, then was asked for model of my phone as I guess he changed something else, anyways after 10 minutes with customer service I have a fully functional skyrocket on go phone, wish this ics update would hurry along, or atleast some info whether it will be an ota or kies download so I can ditch go phone and get a straight talk sim
