Has anyone used one of these? I have found about 5 different apps but all seem to have some sort of issue, fuzzy pics,must do some facebook thing too first, can't edit on album, only works on iphone 4 but not 3s, etc. I would love to give my guest the opportunity to use one of these apps but would like it to be painless on their end to set it up and get the best deal on my end.
Thank you!
