I feel your pain with GroupWise.
However, I support iPhones with Notify Link. Soon will be supporting Android based phones when they release their support for it.
However, Novell is developing DataSync which will sync Android, WebOS, Palm, iPhone, WM, etc, with GroupWise. It is going to replace the GroupWise Mobile Server software. This is rumored to go into public beta in 3 months.
I continue to get questions from my users if they can sync they Droid or Palm Pre with GroupWise. So, this will be music to their ears when we implement it.
The difference between stupidity and genius is that genius has its limits.
When you take things for granted, the things you are granted, get taken.
Even a mosquito doesn't get a pat on the back until it starts to work.
Too many people miss the silver lining because they're expecting gold.
