Well this isn’t good. According to a Reddit thread, iOS is keeping iMessage attachments in the Library/SMS/Attachments directory, even if they have been deleted from within the application. When it is deleted from the app, it is supposed to be deleted from this directory as well. But, obviously, it is not. Here is part of the post from Reddit:
When browsing my device with iExplorer, there was nothing on it. When I browsed my Backup, one location stood out: /Library/SMS/Attachments/. (or maybe /private/var/mobile/Library/SMS/Attachments/ or /var/mobile/Library/SMS/Attachments/)…It had thousands of sub-folders and contained images that I had both sent and received, going back since my last full wipe/restore. Everything. Stuff I hadn’t seen in months. Stuff I had deleted months ago.
However, it is said to have been fixed in the update with iOS 6.1, according to iClarified. As iDownloadBlog points out though, devices that can’t updated to the newest version of iOS aren’t able to get the “bug” fixed. This is a definite problem, with a simple solution though, if you’re willing to jailbreak for it. If you go into your phone via SSH, after jailbreaking of course, you can simply delete all the subfolders from the “/private/var/mobile/Library/SMS/Attachments/” directory. This will delete them. This is done at your own risk, though.
What do you think? Are you already deleting them? Not worried about this? Let us know in the comments, or tweet me @TiP_Kyle.
