Well I moved over to 4.5.056 a while ago. I longed for HTML email. Until today the email was not working in HTML. I thought my software version was broken.
Well today I finally started getting work email in HTML (BIS). I must say I love my Pearl all over again.
Also with the improvements to BIS IMAP I am getting my work email as fast as my coworkers on BES get their mail. Very slick. I even uninstalled the GMail app and started to IMAP that mail again.
