In its One X+ announcement, HTC also announced some changes to Sense. While none were groundbreaking (so don't expect a visual overhaul) and not a lot of details were revealed, the company did mention a few things were being upgraded.

The camera software seems to have received the bulk of the changes, starting with the front-facer, which now includes Self Portrait mode (previewed below, left).
