Just got the DROID X from Verizon and have the small 150Mb plan. I am looking to stop all unnecessary data usage unless I specifically want to use it. I have removed the news and weather widgets from my home screen and turned off "data enabled" and "background data" in settings/data delivery. I am around wifi all day so I can enable that if I want to download an app. Is there anything else anyone can recommend or will that stop the majority of back and forth data transfer from the phone? Thanks for helping a newbie!
