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.
This is quite the update to drop on anxious customers less than two weeks from launch. I can only wonder what other tricks and unknown or upgraded features (PUSH email? HSPDA instead of EDGE?) Apple could be waiting to announce.
Update: 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. Since Apple dropped the "2-year activation required" language from their ads after originally airing them, this might offer more hope to those who aren't able to renew a contract just yet to get the discounts.
Update 2: Commenter Greg points out that Apple's competitive chart shows the Nokia N95 as a no-WiFi device, when it actually does do WiFi. We hope this error will be corrected in short order.
