ComputerWorld points out a little publicized fact that iPhone 3.0's Safari browser will support Geolocation services. This means that websites will be able to request your current location (if you give them permission). Google said they will be launching the Latitude website for iPhone after the 3.0 OS is released.
The iPhone Blog reports that in the iPhone 3.0 beta firmware, users are being told that may not re-download applications over-the-air without being charged. The dialog box (shown above), however, does indicate that users may still re-download applications for free through their computer.
