I've been using 3g xoom for a few weeks and love it. Everything works great. I just bought another wifi xoom for my wife, and am having problems getting some apps to run on it. Specifically, pandora and epocrates (medical app). Both force close when trying to start. I've tried uninstalling, re-installing, xoom reboot, factory reset, and anything else I could think of, but no luck. So far other apps run OK. Anyone having similar issues, and any ideas?
