There's an iPhone 4 that has been getting pretty slow lately, so I figured I'd browse a bit about how to fix it. One particular tip several sites seem to suggest is clearing Safari's cookies.
I am skeptical about this, because, well, cookies are just files that are used when you browse the web. I suppose that clearing the cookies may speed up the browsing experience, but I don't see how can that speed up the overall iPhone performance. In fact, if I have Safari closed, I can't imagine any way in which cookies could affect my iPhone. I mean, it's not like the iPhone is checking my cookies when I am playing Angry Birds or something.
Is there any truth to this tip? Does it actually help iPhone performance to clear the browsing cookies?
