While there's no option to swap the drained battery of an iPhone with a full recharged one, the promised eight hours of talktime and 250 hours of standby time should bring enough cheers to those who are planning to queue up outside the Apple stores at 0600 hours June 29, 2007.

In related news, a new report has suggest that 19 million Americans have strong interest in buying the iPhone, 67% of who are subscribers on other carrier networks.
