Snap panoramic photos on your iPhone for extra-cheap over the next couple of days, with Pano reducing their usual $4 charge to $1.19. They've just released version 4.0 too; with an even better UI and faster shooting-time.
It works by stitching together up to 16 photos with a semi-transparent guide which helps you match together each shot perfectly. It's been around for a while, with Apple awarding it with their 'Best Apps of 2009' accolade, but Pano's put the price down for the next couple of days while version 4.0 is all sparkly and new.
