I decided, after a while, that the time my iPhone rings before it dumps to Voice Mail is not quite long enough. If my phone is in my front pocket and I am sitting in the car with my seatbelt on it is a near run thing to get it out and turn it on in time to answer the call.
So, I went to the Apple Store and talked to a very helpful technician, who said that she didn't think there was an available adjustment. Then, a couple of days later, after getting my hair cut I nipped into the Verizon store, where a very nice young clerk gave me basically the same answer.
Is there anyone out there who knows how to add a few seconds to the ring on my iPhone?
