I am moving from an iPhone 3G (16GB), which was absolutely miserable to use since iOS 4 came out back in June/July 2010. I had a lot of doubts about getting the iPhone 4S, and almost pulled the trigger on the Sony Xperia Play 4G. I got the 16GB iPhone 4S, which I preordered Friday morning. I am wondering if that was a mistake. I'm wondering if 16GB is going to be too little space to work with now that it has a 1080p camera in it. Ideas? Of just post-purchase jitters?
