Hi y'all. I am new to this site and iPhones. I just purchased a 4 s, and a 4 for my wife. Does anyone know a good app to enlarge the keyboard? I've played around with SIRI, but sometimes it is faster to type the text. I am always hitting the wrong keys, though. I have a landscape business and hate talking on the phone anyways when I'm working because I am usually in mulch or dirt. Do y'all know any other good utility apps?
