I cannot identify a specific pattern but my Email Check Frequency changes itself from "Never" to Every 5 minutes. I change it back to Never but at sometime later it returns to Every 5 minutes. In addition, when I set the email notification ringtone from the default setting of the "Droid" sound to something else, it returns to the Droid setting. This happens to my Pacbell email account. I do not want to delete my email account, I just want to control when I check for new email. Anyone know a fix for them problem?
