SaskTel has just dropped the price of the 16GB iPhone 4S, available in black and white to $0 on a three year contract–it’s normally priced at $78.99. There’s no word on how long the sale will last.

Over the past few weeks, SaskTel has run out of iPhone 5 stock for 32GB and 64GB models. The 16GB iPhone 5 just recently was made available online again, starting at $178.99 on a three year term (it beats other carriers by a penny). The 8GB iPhone 4 currently remains out of stock.
