From chris comair come some very fine apps for your i-phone: Polarize and LOFI. Both free at the app store.

Want to add a funky retro look to your photos? Polarize will do the job for you! Polarize is the only iPhone application that will do a series of pixel-by-pixel modifications to your photos, getting that true look. No cheezy overlays are done here.

Polarize gives you:
-A great unique look to your photos
-The ability to write at the bottom of your photos with a custom hand written font
-Any size photo is accepted!
-High resolution output

Check out the flicker project polaroid group and meet the huge community who is in love with that app.
