Does anyone know a way to make my iPhone 4 display a repeating loop of a set of photos on a modern, flat-screen television? For my in-laws' birthday party I want to make a slideshow of scans of old photos display on a big TV. I'd rather not use my laptop for this for a bunch of non-relevant reasons. How can I do this with my iPhone 4? Please help me out step by step. What kind of cable do I need? The TV I'll be using is fairly new and has modern inputs. What application or app would I use to do this? Also, these will be scans of old printed photos, so how can I even get them into the iPhone? Help please! Thanks.
