As the title says. I have a galaxy s2, rooted and flashed to straight talk. I bought the phone flashed and after having the phone number changed my phone stopped working on 3g so I no longer have mobile data. Im wandering if anyone could tell me how to fix this problem? I have been through all settings and as far as I can see there is nothing there to fix my problem so Im thinking its an issue on straight talk side. If someone knows of this problem and can offer me help I would appreciate it. Also if someone flashes phones I have a second s2 with ice cream sandwich update that I would like to have flashed. Obviously I will pay for services
