Yesterday my iPhone began running rough. Transitions and scrolling were not smooth. I figured it was some issue with the Internet. Late in the evening it got worse. Then, to bed. I plugged the phone into the charger. Minutes later it rebooted itself. I checked it, shrugged, and went back to my pillow. It did it again. It makes an unpleasant sound in the night when it reboots, so I shut it off.
This morning, upon starting up, it rebooted itself again. I did a search. MacRumors had a thread on the subject. The solution? A restore. Hold down the power and home buttons for about 25 seconds. The phone goes into restore mode. Connect to iTunes on your computer. iTunes detects the phone in restore mode, and provides instructions. My restore took about 40 minutes. It was relatively painless.
Unfortunately, the thread I used to learn the fix did not have any indication of the cause of the problem. I found several other threads with similar advice, but no indication of the cause. We shall see if the problem comes back. Most users complained of this type of issue after doing some unorthodox or unauthorized software or hardware modifications. I haven't done any of that, so I am hopeful I have found a solution.
If you have a smart phone that syncs with some kind of program on your PC, as the iPhone does with iTunes, it is a good idea to let them talk to each other once in a while. Backups need to be run, and software updates made. Though this modern technology is pretty smart, the operator must still be involved once in a while.
I have found that just a little regular maintenance on my tools keeps them sharp and ready to use, whether a knife or an iPhone. Just a suggestion. Keep up on your updates, and backup frequently.
