HTC Sync was updated a few days ago, and a clever user captured some images from it. Amongst them was the picture above of a phone with no capacitive buttons and no other identifiers whatsoever. It's possible this is just a generic image used as a 'placeholder' for devices that don't have there own design yet, but then why would the picture be there in the Sync if there was no phone it was a 'placeholder' for? Mystery new phone from HTC or logistics error? Speculate in the forums.
