I wrote my first iPhone application!
My 22-month old daughter loves to play with my iPhone. In particular, she likes MxTube, a YouTube downloader app, available if you Jailbreak your iPhone. After a while, she tends to delete my downloaded videos because her click and swipe coordination need some work.
So, I've written an app that backs up my videos and restores them whenever I need to. Ignore the "Background Enabled" message- that pops up when I try to take a screenshot because of another app I have installed.
