  • Why does my iPhone photos show the places they were taken? I noticed that if someone sends me a picture and I save it to my photo album it'll show where the location the picture was taken at. Some of the pictures I take myself too will show the location in my album. I'm wondering exactly why it does this lol
  • Why does my Iphone 4s have 6 gigs taken up by photos? I only have 860 photos on the entire phone and a few very short videos. I have checked the files in the DCIM folder to see if there were some in there that were not showing but there's only the 860 listed. I have no idea how 860 photos could use up that much memory. My friends Iphone has over 2000 pictures and only 2.5 gigs are taken up.
  • What will erase and sync erase on my iphone? I wanted to connect my iphone to a new computer but it says erase and sync, what will it erase? All of the contents or just music?
  • My iPhone says that 7gb of memory are taken up by photos? I only have 161 photos and 29 videos (all average 3 minutes long) in my camera roll. I don't understand how it's taking up that much space.
