SO nobody replied to you question.
i Have same question./ problem.
i Have a full 4s and can't figure how to get the photos perminantly off the phone to make space.
the back up is useless a it's only there in case you need to restore your phone.
i Want to store the data from my phone on a cloud , any cloud , where I can get to it in the same way I access it when using my phone
but nobody tell you how to do that.
i May have to buy another phone because I can't make space on my phone as I don't know where it's gone.
it so confusing.
