I ordered a new flex ribbon/cable on ebay for my N1 because the power button part of the ribbon is broken. When I went to replace it it was the wrong part. It fit in where it was supposed to, even turned on, BUT the LEDs were misaligned and some of the resistors were different as well. I went back to ebay and saw that there is a G5 and G7 version. I thought there was only one version of the N1 other than the radios for AT&T and T-Mobile. I didn't realize there were other differences. The part was bought several months ago but I only now had time to try to replace it so I can't return it or exchange it. Does anyone know what the difference is between a G5 and G7 N1? Also, how can I tell which one I have?
