Is it normal for the speed of the iPhone/iOS5 to be somewhat slow as the amount of free space decreases? For example: When playing a song in the iPod app, I'll change apps, then go back the iPod app, but the app takes about 1-2 seconds to update. Sometimes it will still show a song I had played before the current one. Also, when I lock the screen, if I've been using it a lot, it takes a couple seconds to here the lock noise.
