I sometimes forget that I can make phone calls on my iPhone. I use it for so many other things. Storing tickets for shows. Paying for most of my transactions. Getting much of my work done. Keeping track of my exercise and diet. Ordering things to my house like razor blades, food, and clothes. Watching movies. Reading books. List goes on and on.
Just as a side note, one thing I don’t use my iPhone for is reading Free Republic, the desktop format doesn’t read well on a phone. FR should look into getting a mobile format. I don’t know how easy or difficult it would be to do that but it would make surfing FR on your phone a lot easier. (I know, first world problems)
