Rim is doing another round of server updates in prep for rolling out BIS 2.5 and enabling all the features in the new O.S. (I am running a beta of 4.5 on my curve now and its nice to use doc to go for excel and word) The new updates will enable the HTML email support and other goodies such as OTA updates.. As normal they are doing it when it will have least impact.. Unless you are a pimp in which case your watch will have to handle the load during “pimp Time”.
