Modgrl, my photos are not the greatest, but here is what I'd advise when you have a very basic camera:
*Think about getting a tripod or mount (they do make them for the iPhone: https://www.google.com/search?.....for+iphone)
Having a firm, stable surface that's between waist and head level helps me make sure I'm getting all of myself in the frame, and is more flattering than having a camera below waist level (hello double chin!)
*If possible, try to take photos in natural light away from shadow. (This is not possible for me most of the year; I take my photos in the morning and my outdoor porch is quite shadowed. I'm not willing to waste time running outside, setting up my large tripod, and fussing with the light. So instead I open the blinds as long as it's not dark and turn on as many lamps as I can.)
* There are apps on the iPhone that will make self-photos easier; I like Camera+ (by Smugmug; many easy editing features and a camera timer.)
* The iPhone is quite good at taking clear macro/up close photos in bright or natural light; perhaps your solution could be to take lots of detail shots (close up of shoes/accessories or the fabric you're wearing) in addition to far-away pics.
* Because I don't have anyone else who takes pictures for me, I pick a couple spots in my house that is as well lighted as possible and has enough room to put the camera on a stable surface, stand against a wall, and not have my head or feet cut off in the photo. That way I always know where to stand and can "pose" in a hurry.
