To all Tmobile 9700 UMA users, please let me know what kind of service you're getting. I've always got good service until about a week ago. I'm using Linksys WTR 54g router for the past couple of years. My phone has UMA and wifi icon thats lit, but I'm dropping calls or hardly able to make a call. As soon as I dial it takes several seconds to ring and call failed after a couple of rings. Anyone else having issues?
