I disassembled my Droid X this morning to get at the "external antenna port" on the L shaped motherboard. While I was taking the back off, a little rubber thing fell out of the phone, and I don't know where to put it back during reassembly. It's about 1/2 inch long, 1/8 inch wide and perhaps 3/32 inch tall. It has a hole in the middle and some tab shaped ends. It looks like it might go over a push button as a cushion or something. It's a rather intricate molded rubber piece and probably is important. Does anyone know what it is and where it goes??? Meanwhile, I reassembled the phone and it works normally. Can't tell anything's missing. For disassembly instructions see Droid X Dissected! | Droid X – Blog dedicated to Droid X News and Accessories!
