Most carriers have the iPhone 4 16GB priced at $99 on a 3-year. Future Shop has put on a 1-day sale – directly competing with parent company Best Buy’s “Free Phone Friday” – and slashed the iPhone 4 16GB to free on a 3-year. A tweet was just sent out that “TODAY ONLY! $0 for the iPhone 4 16GB on a 3yr agreement from Telus, Rogers, Bell, Fido and Virgin!”… now you’ll just have to wait until iOS 5 comes out. Tempted?
