OK this year is actually my first year carrying a cell phone in the field. In the past I've had mixed feelings about it. But I finally decided to in the event of an emergency. The trouble is, unless I'm in the truck I miss all the calls. My cell phone vibrates as it rings, but I never feel it on the mower or while operating 2 cycle equipment. I assume the rest of you have dealt with this. So what model has a strong alert and is also Sprint PCS compatible?
