I get to use most of the newest devices and test out all the platforms in my job. My "go-to" phone is the iPhone 4S, but there are features I see on other devices that I really wish were present in iOS. At the top of the list of wants is rich contact integration with my social networks.
Once you have your new iPad all set up, you're going to want to get your contacts sorted out so you can email, iMessage, FaceTime, Skype, and otherwise stay in touch with the people that matter the most to you.
Trying to figure out how to automatically dial an extension on your iPhone? If you're anything like me, you have quite a few friends and colleagues that have extensions to their phone numbers. Luckily, Apple built this feature right into iOS, and the last update made it even easier!
Adding contact pictures to your address book on stock iPhones will only show the contact picture when you actually click the contact. For jailbreakers, there's a nifty little jailbreak app called Cyntact that'll add them inline. Cyntact was actually one of the first apps available for purchase in Cydia. It was also written by the creator of Cydia, Jay Freeman (Saurik).
