Ok, I need some advice. So I have a corporate account. I am currently have the perimer account status with the upgrade option. And there is also another option under the perimer status that says I can do a sweet swap and currently have 150 dollar upgrade on the first line and 50 on the second. Could someone please explain how this works. What does the sweet swap do? The upgrade, what does it apply to, retail or 2 year? Sorry, but in Europe we do not do this stuff. You just walk in buy the phone, and use it.
