Just got off the phone with UPS after trying to set up an authorized release to allow the driver to leave my phone on my doorstep without a signature. The representative said that Sprint has specifically requested that a signature be REQUIRED before they leave our IPhone 4S. Regardless, I am going to leave a huge note on my door with my signature. I'll be at work so I know I'll probably miss the delivery. The representative told me to watch the delivery status, and once it has been confirmed the driver made the attempt and left without leaving the package - I can call and pick up the package that night at the local UPS headquarters. Just a little FYI, thought everyone should know.
