So my iPhone4 must have gotten jealous over yesterday's announcement and starting slowing down and locking up. So I cleared out all the apps in the multitask bar and did a hard reset (by holding down the power and home button for 10 seconds.). It booted up fine, was running normal, so I went to bed and didn't think twice about it. This morning I woke up and noticed that the battery percent # wasn't in the status bar. Then I got a text, and was the default maribma instead of my typical TELEGRAPH alert. I dove deeper into the settings, and sounds, brightness and the battery toggle were all put back to their factory default. Has that happened to anyone else? I've done a hard restart numerous times before, but that never happened.
