Why on earth did you do that? You joined this site a year ago and you knew nothing about the event today and the 99.999% likely chance a new phone was coming out in june/july? You only needed to wait 12 days from when you bought the phone till today.
If anything you should get $100 back because the price was lowered by $100 effective today. Dosn't Wal-Mart give you money back if the price drops in the first 30 days?
