Looks like I'm going to have to pay the $120. Admittedly, that isn't the end of the world, and considering how many times they've given me a new replacement phone with no questions asked, I guess I should stop my b*tching and just do it
I tried clicking on the "Take advantage of open enrollment in Total Equipment Protection during May" link, but this leads me to my phone/plan overview page with nothing else to click. I bet it checks whether you got the phone in the last 30 days or not. Either way, I guess I'll sign back up for that.
