Just a thought, why not make a PASSPORT variant with a dual SIM?
Admittedly, Blackberry's relationship with the carriers hasn't been as rosy as it has in previous years. We saw this in Canada with BB's move to sell phones direct to the public because of the store-front promotion issues they've had with carriers. I would assume no carrier would stock a dual SIM phone they intend to release on contracts.
Dual SIM's may not be a huge lure in the general consumer market, however I personally know at least 6 people who would buy a business blackberry with hard cash today if BB came up with a dual-SIM device. Question, is this a viable idea for a premium "limited release" BB business phone to have a dual SIM variant...or are there perceived negatives in your opinion with associated with dual SIM BB device? Would you buy one?
