This might be a dumb question but is there any way (or app) that would allow us to change the white envelope in the notification bar for email? I ask because I have 2 accounts, one Yahoo and another Exchange for work. I never know which email account gets a new email unless I expand the notification or enter the email app. It would be great to be able to have a little "Y" icon (or something) for a Yahoo email and another icon for the exchange email. That way I can just ignore all the exchange email that comes in after work and only bother looking if it is a Yahoo email. Anything out there?
