Apple's next iPhone won't be until late 2016, but should come with a new design.
iPod Touch Firmware 1.1.2 Released: Add Calendar Events [Update: Jailbroken]
Early reports indicate that the new iPod Touch update provides "Add Event" functionality to the iPod Touch, confirming an email exchange from Steve Jobs who promised that edit and add calendar events would be coming in a future software update. The lack of calendar editing had been described as a "bug" by Jobs.
While the iPod Touch 1.1.2 and iPhone 1.1.2 updates are likely very similar, there may be device specific issues. Please keep comments on topic in their respective threads.
Update: TUAW reports that iPod Touch 1.1.2 has already been jailbroken. Details are forthcoming.
