Hey everyone I just took my TE2 apart (battery replacement, finally got it from Hong Kong!) and put it back together, then discovered I lost this same piece. (It actually somehow fell down in my shirt, which is where I found it! ) Wow, it is REALLY tiny! I remembered reading about this mysterious little part in the past, though it took some real dedicated searching to figure out where exactly this thread was. I'm relieved that I was successful! I actually found this thread through another more recent thread. I'd like to suggest to the mods that this thread get "stickied" and re-name it something to the effect of, "What is that tiny piece that was left over after I took my Tungsten E/E2 apart and where does it belong?" I think it would be helpful for others.
