No, i do not have the app as I do not require a cell phone. if I had a cell phone, I certainly would NOT be texting while driving that is for sure..
I do have a question about the app though....does it disable PHONE CALLS, or just texting capability? I couldnt tell from your post if you were "calling" your friend, or "texting" them to see if the app was functional while the website was down....plz advz
