According to Mexican technology site canal-mx, Apple will be reengineering its iPhone 4 antenna design to deal with the antenna-gate issues. The new redesigned phones will be available after September 30.

We have no way of knowing if this is true or not, but it would be good news for customers who purchase an iPhone 4 after September 30. What about the existing iPhone 4 though? Can we swap out? Doubtful.
