Why Is MDS Required?
MDS means Mobile Data Services, which is explained on this web page at Research In Motion. MDS is a feature of BlackBerry Enterprise Server (BES). The simplest english to the layman is that MDS essentially makes full Internet access possible on your Blackberry. Without access to MDS, it is almost as if you are behind “The Great Firewall” that blocks all ports except for email and WAP, limiting your ability to use your Blackberry. The original market for Blackberries are corporations, and this is why a server solution is marketed. A medium and larger size corporation generally has no problem getting a Blackberry Enterprise Server solution set up. However, these days, the Blackberry market is diversifying and there are now more and more individual and self-employed users of Blackberries, and do not need all of BES features.
