I use the phone camera all the time. I am still a newbie and use some tools that I used when I was working (retired and lovin' it) and graph paper and markers work well also. I take pictures of all stages of my quilting. From the stack of fabric, to the blocks as I lay them out, my flannel board, my practice layouts of the blocks, I just grab the phone and take pictures. As a new quilter, I find that uploading them to my iPad or computer helps me to remember exactly what I had in mind when I started. Also, change things after I look at a picture and go "wow, that doesn't work". Find the new technology works well with the old technology of quilting.
