Hacker Conrad Kramer has unlocked a panoramic function of iOS Camera app.
According to Kramer, the trick is to set “Enable Firebreak” key to “Yes” within a preference file of iOS.
Alternatively, the Firebreak tweak by hacker Grant Paul which recently became available at Cydia storefront, could be used.
Once the Firebreak is installed in the jailbroken phone, it will allow you to take full panoramic shots directly from iOS interface. So far there is no word on when Apple will make this functions live.
