If you're so worried about pre-signing then worry about a dishonest driver pulling up to a location close to your home, signing for the package themselves, and taking your iPhone and selling it. All I'm saying is that there are many ways and many places for your iPhone to disappear to if a person wants it. Not that I wish that on you, but pre-signing isn't the worse thing that could happen to you since you mention not trusting anyone. If that's the case you should wait til you can buy one directly at the store... because for all you know that box from UPS or FedEx could have been opened and resealed and when you open it there could be a small brick inside!!
