The ups/usps thing is certainly annoying. Once ups puts it in usps hands, it sits there for days. If anyone ships something that way, I order from someone else, even if it's a little more expensive. I've received updates just like yours and suddenly, it then moves on. Give it a little more time. This type of delivery generally takes a couple weeks from my experience.

I seem to remember reading somewhere that it isn't exactly a partnership, ups just found a loophole with the usps and is taking advantage of it, and the usps isn't exactly happy about it. That could have something to do with why my packages sit in Kansas City for a week, EVERY time it's shipped like this.
