Every time I go to update an app, I get a triangle sign with an exclamation point in it, and the message that Download size requires Wi-Fi. I have never had this problem in the year and a half of having my Droid X. Did something change in the last month or so? It happens when there is an update on an app or if I go to add a new app. It just acts like its going to install, and then I get the sign above. HELP??
