Good to hear that your power button works again. The problem with your proximity not working is probably caused by a missing filter on your new flex. Most flexes nowadays get shipped without this filter. You have to transfer this filter from the old proximity sensor to the new one. That will most certainly do the trick. Have a look at the following picture: http://www.beijingiphonerepair.com/wp-content/uploads/2011/08/proximity_sensor_location.jpg The part pointed in this picture as proximity sensor is the one you need to be looking at. This particular one is also missing the filter by the way. Just check your old flex if it has a filter (with a small foam boarder) on it and transfer it to your new one. Good luck and please let me know if this solved your problem.
