  • Why on my iphone does it sometimes show texts in green, and sometimes in red? I have a iphone 4s, my son has iphone 5. Sometimes when i text him, the text appears in green, and sometimes it appears in blue. Does anyone know why this is?
  • Why does my iphone sometimes connect to Itunes and sometimes can't? Sometimes i can connect my iphone to my computer and it says iphone apple device. But sometimes it says device unknown? Can anyone help on this? Also, my Itunes need to open so my iphone can connect. I don't know why.
  • What do people use to take selfies of themselves taking selfies? I have to help someone take a good selfie for her profile but I can't exactly explain it. As far as I know, the front view lens only captures you and your background and the rear facing lens on the back of the phone takes a picture of what is in front of you, such as a landscape. That said, using an iPhone 4, how is it possible for someone to take a selfie that looks like there's someone taking a picture of them while they're doing it.
  • What could be causing my iPhone to not be holding a charge? It's an iPhone 4, and I've had it a few months short of two years. I've taken good care of it, it's got plenty of memory, updated software, I'm not running many apps (I double click the home button to close them often), but my phone's battery won't last at all lately even when I don't use it very often.
