I feel your pain my friend. I had BB's for 10+yrs. Eventually the software my company uses received so much more iOS support than BBOS I had to jump ship just to have the functionality everybody else had.
I spent about 2 months working out the kinks, but now my iPhone does everything much more flawlessly than my BB ever did.
I will say though, my last Bold is still sentimental to me. And still works perfectly.
