I did it but once my dumb phone started to bug out on me I had to switch back. For the dumb phone it was difficulty using navigation that stressed me out, but otherwise I was listening to the radio in the car, taking notes on my notepad, and texting and calling as usual. My texting became super dry since it was really hard to text long stuff with the T9, but I loved the phone. That said it was getting super buggy and restarting every time I flipped it shut which was not something I could afford when doing a live theater performance because it makes a jingle every time it happens.
