My new sup has and uses an iphone. I recently acquired one myself, and I find it to be an excellent tool for communicating and maintaining an increased level of accountability from my management team. If there is a problem or an issue or some other thing going on out on my route that requires action on the part of management, I will communicate it to my sup via text message, a record of which is stored in my phone. Compared to some of the old farts I have worked for over the last 26 years, my new sup is very good at following up on issues that I bring to his attention in this manner. He doesnt always tell me what I want to hear, but if he doesnt have the ability to solve a problem then at least he is honest and communicates that fact to me rather than blowing me off or conveniently "forgetting" that I warned him about it ahead of time. Once I text him about a problem, my ass is covered and its his problem now instead of mine.
