I just visited the website www.businesssoftware.nokia.com to see if there was a new module of blackberry available because mine started to malfunction like 3 weeks ago and now i see they removed the link.
That seems to me that the carriers are not supporting the blackberry service in non RIM devices, that sucks!!

Still seems to be there for me.
