Hiya, I recently bought a HTC One X, which was locked to Orange (and as such has all the Orange nonsense on it). I've had the handset unlocked so that I can use my O2 sim card in it, which works fine apart from the fact that I can't set up another APN profile to allow me to use my O2 mobile data settings. As such, I'm unable to use mobile data at the moment. I can manually set up the APN profile, but then after I've saved it I'm unable to select it. I can see it there, and when I go into it, all of the settings are correct (O2 sent me an email with a step-by-step guide). Does anyone know what the problem might be? Am I doing something wrong or is it just a limitation due to the fact that the handset was originally locked to Orange (and as such has the Orange APN settings as default). I've posted a thread in the Root section too, as I'm unsure whether I need to install a different ROM to the handset. I'd prefer not to have to, as I'm not confident enough to attempt it, and the amount of different options out there just confuses me. If someone could explain what I need to do in plain English, I'd appreciate it! Thanks in advance for your help.
