  • Why does my iPhone keep telling me I've run out of storage data? My iPhone keeps notifying me that I've run out of storage. If I try to take a picture it tells me I don't have enough storage to take a picture. I've gone through and deleted pictures, songs, and apps but half an hour later it notifies me again that I've run out.

  • On my Iphone 4S. How do I lock a received text message so I don't accidentally delete it? I use to have an Android and there was a button I just pressed and it locked a message, saving it in case I accidentally deleted the conversation. My Iphone 4S doesn't seem to have this feature. Anyone know how I can easily lock text messages received so I don't accidentally delete?
