In a press release today, Apple has revealed a number of significant upgrades to both the iPhone's battery life and touch screen. Instead of what I believe was around 5 hours of video/talk and 16 hours of audio playback, Apple has updated the iPhone's battery life rating to the following numbers: up to 8 hours talk time, a whopping 250 hours of standby (over 10 days), 6 hours of internet use, 7 hours of video playback and 24 hours of audio playback.  In addition, Apple has changed the spec of the original 3.5" plastic surface of the iPhone to "optical-quality" glass, which should bring some smiles to those who were concerned about the durability of the phone's primary feature and user interface. Interestingly, this latest press release also mentions the iPhone's pricing - again at $499 and $599 for 4GB and 8GB, respectively - but makes no mention of contracts being involved with those prices.
