Late last week, we reported that Apple had posted an online availability database showing iPhone 3GS stock levels at each of its over 200 U.S. retail stores. At the time, the database showed solid availability of the new iPhone, with nearly 90% of stores showing availability of all four iPhone 3GS models and only five stores being completely sold out.

Apple's retail store stock levels declined over the course of the weekend, and the availability database is now showing significant iPhone 3GS shortages. According to the database, only about 40-45% of Apple's retail stores currently maintain stock of all four models, while nearly 15% of stores are completely sold out. Three states are currently listed as being entirely out of stock of all four models: Alabama (two stores), Oregon (three stores), and Utah (one store).
