Apple today released iPhone Software Version 1.1.1. Most significantly it adds the iTunes Wi-Fi Music Store, and is a full software upgrade, weighing in at 153 MB.
The update also enhances the ability to use the Home button to control music, patches security bugs in Safari and Bluetooth, adds TV Out (using the new iPod AV Cables). It also adds a battery status icon to the menu bar for the Apple Bluetooth Headset. In addition, some widgets have been improved (stocks and cities can be moved around in order). Apple has also offered an option to disable EDGE data services while roaming (to prevent international roaming charges).
