Does anybody know when the HTML support will be available for Blackberry Professional server? The latest BPS is still 4.1.4a, isn't it?

yah you are going to have to wait for RIM on that one... Not sure what they have scheduled for BPS... If/When they do it, it should be in BPS 4.1.6.

Is there a work around?

hmmm I have never heard of anyone doing this but.....

(and I dont recommned it)

you could....

Take note of your current BES name.
Backup your Database.
uninstall BPS BES
Install Full 4.1.6 BES with same BES Name and within the Same DB.
