iPhone Software Update 1.1.3, a free software update available today via iTunes 7.5 or later, brings significant new features to iPhone. After installing the update, iPhone customers will be able to automatically find their location using the redesigned Maps application; text message multiple people in one message; create Web Clips for their favorite websites; customize their home screen; and watch movies rented from the new iTunes Movie Rentals right on their iPhone.

I just updated to iPhone 1.1.3 - and had problems. 1) I plugged my iphone into itunes on mac and clicked CHECK FOR UPDATE. I then clicked yes to download new update. The iphone had a problem and said it had to do a restore. It then occurred to me that I had better update to the latest version of iTunes. After installing latest itunes, I was able to finish the install, and get up and running on 1.1.3.
