Do I need to unlock my phone to use Consumer Cellular?
I bought a used Iphone 3GS that was an AT&T phone and I was planning to use it with Consumer Cellular who said that I wouldn't need to unlock the phone to use their service. When the phone arrived it worked fine, I didn't have to go through any activation, it just went straight to the home screen. After inserting a SIM card and calling to activate it, the phone continued to work and I was able to text/make calls. Then it said it needed to be updated so I plugged it into itunes and let it be; when I checked on it it had restored itself and now I can no longer get into the phone. All I get is the activating phone screen and it won't recognize my SIM anymore. I bought a new SIM to see if that was the problem..still won't work. Why would it work one minute than just stop? Does this mean that I do infact have to unlock the phone to use it with my new service??
