No sim card problem
My nexus one obstinately refuses to recognize the sim card that I insert in it. It is not sim-locked, as no unlock code is asked. Instead, the usual message appears: "no sim card, emergency calls only". Well, I guess the sim card tray is dead, unless you have other explanations..? There is a good Ifixit tutorial to replace the sim card tray, but I have been unable to find where I could by the part.
Thanks for your help!
