I've been apart of almost every iPhone preorder and major Android flagships and just want you guys to know that the systems and information that has been sent to you is not always indicative of where they are in the process. For instance, although your order on the website still may say "processing" or something like that it could really be past that part in the process and preparing for shipment. They could already have tracking numbers for many of these devices but they simply haven't posted yet to accounts.
So don't get worried if you don't have a tracking number by early next week. Chances are by the time many receive tracking info, it was prepared several days before they let you know it was. Just want to assure you these things are typically seen with preorders. So try not to freak out when your fellow AC forum member gets a tracking number on Saturday and you didn't. That does not mean yours is not that far along in the process. Just means they haven't gotten to send the info to you at that time. So this type of stuff all the time. Even with regular orders we place but of course we may not pay attention as closely with as much anticipation and nervousness. So plan to go into the weekend without tracking info but don't be alarmed. And honestly, there would be nothing you could do that late that would speed up the process anyway lol.
So just speaking from experience. I no longer get worried about this stuff anymore. I order and expect it to come by the release date no matter when their systems are updating with administrative information.
NOTE: This is from the perspective of dealing directly with carriers. Not Samsung.com
Also, in regards of Samsung free gifts. Never had an issue with it. People here are getting overly nervous about how many free units will be available. Don't worry. There will be enough for those that preordered. The process is easy. A quick form to fill out, copy of receipt and that's it. Don't worry here either. You'll get that as well. Good luck guys.
