Is it time to upgrade?
iPhone 5 come with a host of new features, including a panoramic camera. However, could only capture 240° of scenery. Here I find a better solution. With a attachable fisheye lens, now you could capture full 360°(H) x 180°(V) panoramas. Further more, it would also allows you to record 360°(H) x 90°(V) or 180° x 180° panoramic videos.
That's HotPano mini. I'm tempted by it for my iPhone.
