Yay! I fixed my treo

I broke my Treo 680's screen a week ago by accidentally tossing a remote on the bed right on top of where my cellphone was. Ordered a replacement screen off of ebay and a Tx5 from Sears.. Yes I replaced the screen myself. While doing it though I dismounted the microphone so now I can hear the voice but they can't listen mine. Perfect as a spy gadget but need to fix it. For now, thank you bluetooth headset, at least I can use it for meaningful conversations.
