I believe I can be of più assistance. I recommend downloading a Minecraft skin maker app on your iDevice. If your skin maker app happens to have an autosave function, te should know that there's no way of deleting this. It will automatically save every pixel te modifica and will be a lifesaver, should the app crash at any dato moment. The app is easy to use. te can choose from a variety of premade Skins and modifica them. Know the Minecraft username of one of your friends, o a different person? te can tap "Search da username" and te can type in the username. Be warned; cerca da username is case-sensitive. Once the skin is edited to your liking, tap the "Preview" button and find the "Upload to Minecraft" button. This will swap out your current skin for the skin te just uploaded to Minecraft.
te can go on Planet Minecraft, go to skins, and cerca what skin te would like, click one then scroll down to find "Download" then click Change My Skin! and then log in, and your skin is there! :D
