So you can buy this warranty for what, 80 bucks with this deal? Let's say you drop your iphone 4 32GB and shatter the face. If you have ST, you submit a claim to ST, let them send you a box, then you send them the phone, and they repair it, and send it back to you, charging you another 50 bucks. So you are out 130 total, and you had to go a few days without your iphone.
Now let's say I don't have a ST warranty, and I drop that same iphone. I load apple.com, sign up for a genius appointment, and head in. Maybe I'll get lucky and a nice genius will fix me up for free, and if not, they'll replace it with a refurb for 199. So 70 bucks more, but much shorter downtime period.
And I'm not even sure the 80 bucks is an accurate quote on that price.
