Every iBook G4 model prior to the mid-2005 model from Apple can be Build To Order (BTO) with internal bluetooth support. The problem starts if you did not BTO a bluetooth model when you purchased your iBook G4. First of all, Apple might not want to sell you the neccessary four parts needed in order to install bluetooth yourself. And if they do want to sell it to you, it usually cost over $80 in parts only. What would you say if I told you there is a way to add internal bluetooth support to your iBook G4 for under $10?
