I found my cell phone that I had 4 years ago, and I realize there's a picture on it that I really want. There is a SIM card in the phone, but I'm not sure if the picture is saved to the phone or the card. If it's saved to the phone is there any way I can get it even though I don't have a power chord? Can I take it in to At&t? If it is saved on the card what do I do? Thanks!
