I have my 4S delivered last Friday. Siri is a worthy addition from the outgoing model. Siri can also be witty, funny, and polite at the same time.The IOS5 appears to make apps load faster. No more itunes app. Newspaper and magazines can be purchased in a new app called newstand. Icloud is standard with 5gb of free space. Firmware updates can now be accomplished wirelessly. Everything works great as expected from an Apple product.
