Hi,
You've done a good and useful overview of the AP+BP architecture, but I think you need to rethink describing this as something that differentiates a smartphone from a feature phone.
I agree that there's no industry definition of feature phone vs. smartphone, but I don't agree with your suggestion that a feature phone has just the BP and a smartphone a BP and AP. For me, a feature phone is voice calls plus some features (music, camera etc.) and smartphone is voice calls and installable native software (i.e. not J2ME). It's a marketing difference more than anything.
Regards,
Frans

Hi!
I've written an introductory text on GSM mobile phone architecture, and before officially posting/announcing it, I thought I'd invite the members of this list to do some review and give feedback!
