I've got an AT&T 32 gig 4S I got on launch day. I have about 14 gigs of music and a gig of apps; it's half full more or less. I keep the emails empty, I delete all the messages, and all the photos. In other words, I keep the phone cleaned out so it doesn't bog down. But over the last couple months ago, I've noticed a small degradation in performance compared to when it was new. The camera takes a few seconds to open whereas it used to be instantly, pulling up safari and some other things take a little longer than they used to. Any ideas? Running the most current iOS software.
