There is a bug in webOS 2.0.1, where the feature that allows one to re-organize the display order of multiple email accounts, does not work properly. For example in the email preferences where it list the different email accounts, if you press and hold an account it will allow you to move it around in the list order. However, the newly arranged account order does not affect the ACTUAL order as they are displayed in the main email list under favorites. It only changes the order of the list of accounts below the favorites drop down.

This occurs on a verizon or unlocked pre 2 running webOS 2.0.1
