What are the two indentations at the top of the Jam?

- the two small square holes to the right of the sd slot?

I originally thought they were infrared, but then i saw that HTC decided that it was a good idea to put that on the right edge at the bottom (go figure!)

You can put a strap there to carry it with or a lanyard to carry it around your neck.

My Sony Ericsson's strap does not fit in the hole...??

Darkcell,
I put my Sony P800 strap in the hole at the top of my jam...you need to use a small paper clip to push it through the hole.
