considering what type of company they are (el cheapo guerrero), it would most likely depend on the licensing fee for the technology...
...but i would think they would, assuming the handheld was popular (not really sure if it ever took off, but i'm sure the mobile business being abruptly sold by Siemens wasn't exactly what RIM had planned for their first major release of BBC - atleast i saw it a lot on their documentations with images from other RIM-made handhelds). the SK65 was certainly a cool looking phone.
