....(snip) When they launched the S3 I'm almost certain the phones were arriving a couple days earlier than the stores were getting them.
Yup I can confirm that they shipped the S3 a few days earlier. I had pre ordered the S3 and went tho the same sort of thing as y'all with the S4 are now.
I did pre order the S3 and got it about a week before it was in stores, and assume the same will be true with the S4 .
