Quick questions: What are the benefits of forcing the 4400 into digital mode? I read somewhere in the forum that you can do this, but that it might cause more dropped calls. Any experiences? good or bad? Also, if I do force it into digital, will I finally get a D on the display? Will it be functioning off a digital signal only, instead of a 1x? And, if notice that it makes everthing worse, is there a way to "unforce" the phone from digital mode? Guys, I'm on my second vx-4400, and both phones have given nothing but echoes. I want to force the phone into digital mode to see if this helps. Am I wasting my time? Does it make any sense to do it?
