I was tavreling just with my iPhone 5 16GB and needed more space to be able to film, but I don't get any way to erase/remove at least on album in order to get some space.. so I lost the moment..cann't film it.
Apple is known they think so much about all the situations but it looks like they didn't think about this so comom issue for peopole way from home or work;
At least, maybe there is a way, but still didn't manage to find it, so I do I missed the opportunity to save (film) the moment...
