Hi, I just recently switched from a sidekick 3 to a blackberry 8700g and I was upgrading it to the new OS but I was wondering if it's really necessary to install the DOD root certificates and MDS runtime? I want to have as much memory as possible so if I don't need it please let me know! I've searched but I'm getting mixed answers. Thanks in advance.

No, they are not required.

Thank you.

btw, what is the BlackBerry MDS Runtime for? just wanted to know
