In its latest desperation move, Blackberry says it will pay up to $550 to anyone who trades an iPhone for a Blackberry Passport.

The deal kicks off on December 1, but it’s not worth waiting for even if you are the rare bird who’s looking to defect from Apple. Blackberry actually has a better deal going on right now.

When the trade-in program begins next month, Blackberry will offer anywhere from $90 to $400 for the iPhone depending on the model, along with a flat $150 for all models, paid as a Visa gift card. The normal price of a Blackberry Passport is $700 off-contract, so it’ll cost another $150 at least to make the switch.
