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).
To get Cyntact working on your phone, it's as simple as installing the app from Cydia. The current price for Cyntact is $1.00 (USD).
If for some reason you don't see them, respring your phone again. This has happened to me once or twice and a respring fixed it. It only ever happens on a new install of Cyntact. It's a dead simple little tweak but still remains one of my favorite jailbreak apps to this day. If you guys try it out, let us know what you think!
