iPhone apps that'll make your new photographs look old are nothing new. But what about taking your old photos and turning them high-tech? ShoeBox is looking to help preserve memories — the shoebox of photos we've all got stashed under our beds and in our attics — by letting you use the iPhone's decidedly excellent camera to shoot the old pictures, crop them, annotate them, and upload them to share with friends and family. It's a simple concept, looks easy enough to use, and — most importantly — digital images last a whole lot longer than physical photographs do. The app's available now as a free download.
