I ordered the BB 8700C from Amazon.com today planning to convert to Cingular and keep my T-Mobile phone number which I use for business.
It never occurred to me that I would have a number portability problem since I checked on the Cingular site before placing an order with amazon. However, in parsing through all the stuff on amazon, I found this:
Cingular and Amazon.com have not yet established a method for customers to transfer their current number to a new Cingular account. Unfortunately, in order to port your previous number, Cingular will cancel the account that Amazon.com activated and will activate a new account with the ported number. This process makes you ineligible for the Amazon.com rebates.
We hope to offer a porting option in the coming months, so please check back.
So I can either get the $150 rebate or keep my phone number but not both. Well, now I'll have to explore my options for cancelling and/or returning the phone.
