When I checked the UPS tracking page, I was surprised to find out that I had ordered "World Ease", however. I thought it was an iPhone 4S
World Ease is a UPS delivery service: http://www.ups.com/content/us/en/shipping/time/service/value_added/worldease.html
Thats the shipping method, aka the UPS "product".
Your phone is fine, 0.40kg package weight matches all the others.
