Another confirmation that this works for T-Mobile users using the same procedure above. Thanks.

Only things I don't like are:

1. When you get new email, it doesn't highlight which of the mailboxes has new email so you end up wasting an extra step to display the inbox folder.
2. It doesn't update the email having been read so when I log into my email account through webmail or email client, the emails are still marked as unread even if I read them through the phone app. (Or am I mistaken?) Update: Looks like I am mistaken, think I needed to change the update interval setting.
