I am having problems backing up my iphone 4s. It keeps telling me i dont have enough space in the cloud to do so, which is almost impossible as i have selected almost nothing to back up, and have added up everything and it comes nowhere near the free 5gb.

I am having issues backing up my iphone 4s. It keeps telling me that there is not enough storage space available in my icloud, which is impossible as i have selected the BARE mininum to back up. I have also added up everything that is trying to back up and it comes no where near the free 5gb thats you get. At this point i have done EVERYTHING i can to make my phone as empty as possible and its still not enough. It almost wouldnt be worth backing up because i cant back up everything important. Is anyone else having these issues? I almost feel as if its a scam to make you purchase the extra space in the cloud. Its also trying to tell me that i have 8.1GB that are needs to be backed up and i KNOW thats not true... HELP!!!

As a sidenote, yes, this phone is the only apple product that i have, and the only one backing up to the cloud...
