IPhone 4s will not install the 7.0.3 Software Update.

Question

I have an iPhone 4s. It will not install the 7.0.3 Software Update (nor would it install the one prior). However, my friend who has the exact same phone, with at least double the pictures, and probably about 10 more apps, had no problem doing so, though she bought more storage anway and suggested I do the same. I bought the 10gb, for a total of 15 on my phone, deleted the few apps I had, and started to do backups to icloud.
Not only are my images missing from icloud when I log in (even though when I check the icloud settings in my phone they should be backing up), but I still have not been able to do the Software Update. When I go to 'Storage and Backup' in my phone it says 'Total Storage: 15.0 gb', and 'Available: 2.3 gb'. These numbers never seem to change, regardless of doing backups and deleting things.
Does anyone know why this is happening? Any help would be greatly appreciated.
1. Why aren't my pictures there when I log in to icloud?
2. Why can't I update my phone?

Having more storage in your iCloud account does not expand the storage on your phone.  If you don't have enough free space on your phone to update, you'll have to delete some data to do so (such as deleting all your music, then syncing it back to your phone after you update).
Also, backing up your photos to iCloud only allows you to restore them to your phone later if you ever need to, it doesn't allow you to access the photos from iCloud.  It also doesn't give you more space on your phone as it only backs up your photos, it doesn't delete them from your phone.  If you want your photos in iCloud, turn on photo stream.  This will actually take more space on your phone, not less, as you will get a duplicate photo in your photo stream album to the one in your camera roll.
If your storage isn't increasing as you delete data from your phone, try deleting your iCloud backup and backing up again.
