BestBuy.com has the iPhone 4 in White or Black for $49.99 with a two-year service plan on AT&TVerizon or Sprint. We have seen many price drops of the iPhone 4 throughout the last few months, but most were specials or small drops. This one appears to be more permanent and may last through to the new iPhone launch.

What does this say for when the new iPhone is released? Will the iPhone 4 be free on contract or will it continue to be $49.99? If I had to guess, I would say it goes free in October with a two-year plan…if you can wait that long.
