Have been thinking it over for a few weeks and finally decided I wanted to go ahead and get in on the first batch.
Not sure if the receipt number is PII, but better safe than sorry.
I almost regret not paying in full and getting the 2 free back covers, but I don't really bling my phones so figured I'd just opt for a place in line instead.
In my mind, these will ship in August/September. I'm basing that on literally nothing, but it feels about right. I haven't seen a video or any promo material that didn't look like they were holding a mock up device, so they probably don't even have one yet.
