I have a new favorite iphone app, it's called SwankoLab, it's by the makers of Hipstamatic which is another of my favorites. The downfall to me of Hipstamatic was always that I had to use it to TAKE the photo, which was slowing me down. I wanted it to be an app I could apply to images AFTER taking them. Enter SwankoLab, it has the fun mixing of various options, and packs of goodies to buy, but I can apply them to existing photos! If you come up with a combo you like, you can save it and reuse it in the future without having to memorize it.
