Well, I would suggest the partnership between blackberry phone seller and provider of blackberry unlock services.
A phone seller could sell many more blackberries if they are unlocked.
A blackberry unlocker could make much more money if phone seller contacts him directly. Because of bulk and of clear understanding by the seller what must be provided to unlock the phone, an unlocker could even cut the price of his services.
So, folks who do unlocking, do not dismiss this guy and it would be of your business interests to contact him privately and ASAP to establish mutually beneficiary business partnership.
