I have an iPhone 3GS running iOS 6.1.3, I've only just noticed but my backup to iCloud is nearing it's limit of 5Gigs.
I checked my iCloud backup options on the phone and noticed a high amount of pictures/video's in my camera roll:

So I set about deleting any unwanted pictures/video's from my camera roll and got it down to about 800megs:

I then went back to my iCloud backup options on the phone and it's still stating my camera roll as being 3.2GB.
Digging deeper into my usage settings on the phone :

And it shows the correct size for my pictures/video's etc.
What gives? Why is my next iCloud backup still going to be 4.7GB? And it's still showing my camera roll as being 3.2GB in size when it should be 826MB? I've had to buy more iCloud storage until I can sort this out!!
