A few more questions please:

a) Subjective opinions from iPhone --> Blackberry Curve users: Worth it? Why? What did you learn was better/worse? Missed features? Regrets? Returning?

b) The BB plans are spendier, comparably speaking, yes? (may as well use it for work, then; I think they pay some subsidy of data... no idea... have to check the intranet).

c) For the Premier plan I recently upgraded my wife's phone, and now 'Upgrade Phone' is no longer an option for her. Do I run the risk of not being able to purchase new phones now for the next year/two years?

Thanks again!
