Trying to deal my my data connectivity issues, and am looking at the Sleep Mode options in the Power menu. I have been losing 3G connectivity (stuck in 1X) and also completely losing data connectivity randomly over the last couple of days. I did a complete factory reset this morning, and am now looking at the Sleep mode option as a possible culprit. It had been set to "Automatic" by default. I have now set it to "Never". Are most of you leaving it in the default setting? I am really hoping that I can lick this problem today!
