Aug 22nd only applies to iPhones bought in July. You have 30 days from your purchase date and an ultimate deadline of 30 Sep.
One thing I'm wondering.
I'm going to order an iPhone off the apple website sometime in the next couple of days.
The availability is 3 weeks, and it seems to be taking around a week then for the phones to actually be shipped to the address. Which is about 30 days.
So would I still be able to do this when I get my phone?
