blackberry management center
Saw this entering the Beta zone on berryreview. It seems like this could be a great product for a family on a family share plan all with blackberrys if done correctly. Now that RIM had aquired Tungle.me adding a cloud based calandar with web access that can be shared by all members of a family would be an EXTREMELY useful tool. Anyone with kids knows that keeping sporting events, doctors appts, school events, etc... is a pain.
I have been using google sync but it can be a major pain, I would love to see a first party solution.
