I just received my 4th v400 replacement from Cingular today and I am having a problem with it already!! I switched from my old V400 with a full charge on my battery and when I put it in my "replacement" it says the battery was dead! so I charged it and 10 mins later it said charge complete. took it off the charger and about 10 seconds later it goes from being fully charged to one bar... what is going on?? Is this a known defect or what. I have had nothing with problems with moto phones with Cingular. I had the v600 and had two of those and now I'm on my 4 v400 with problems. What is the policy for getting a different model? I am willing to re sign my contract or pay the difference for another model....
