I have jailbroken my iphone 3g on firmware 2.1 and am trying to get hold of ISMS. I go to installer, then all packages and scroll through. There is no isms. There are no end of carrier bundles, but nothing referring to isms.

Do i need to install something else or am i missing a step?

I've tried searching for isms on the installer app bar and nothing comes up here either.

Any ideas please?
