questions about my new TP2

[turbochris]

Here I go again, new phone, new obsession. Nothing else will get done for a while because I can't stop myself from f'ing with this little marvel of technology. I already like it more than my TP and I'm just getting started.

1. will the headphone/usb dongle from my TP1 work with this thing? I used it to get TV out on my TP1, what's needed to get TV out on the TP2?

2. What are the weird looking sensor things on either side of the camera?

3. What's the little button under the camera with the little microphone symbol for?

4. On the opposite side from the volume buttons, there's a little hole in the slide off cover back cover that lines up with another hole under it in the main case, what's this for?

5. under the cover between the SD card slot and reset button there looks like a smaller card or something stuck in there, what is it?

Sorry to be such a pia, I have the tech disease.
