I have a Palm Treo 750 with Slingplayer that worked great for 2 years, but for the past 3 months will not work anywhere in the area where I work. It works fine at home and in other areas. I reported it to Sprint a month ago and there has been no fix. My contract is up in July and I will move to I-phone then. I cannot use any internet applications including Sprint TV or radio. I hate playing for a data plan when nothing works where I want to use it, when it was not an issue for 2 years.
