iPhone 2G- How to delete files

[ajhillgolf]

I had to restore and instead of wiping all files before restore, all the existing files seem taking up about 3GB of space and not "linked" to anything. Is there an app to delete these files? Or do I just have to wipe everything then restore again?

You can jailbreak than wipe them off... but um... unless it's jailbroken, there's no other way.
