I have an iPhone 4s, updated to iOS 7. For a while now, when I look under Settings>General>Usage, it says the saved messages are taking up 6.1 GB of space on my phone! I only have a 16 GB phone, and I would like to actually be able to use this space! I delete my conversations every day, I restored my phone to the factory settings and restored it from a backup, and have searched everywhere on the internet for a way to fix this but nothing has helped! Please help me!!
