I guess the problem with embedding the 3G radios in ALL devices is that 1) Mfrs cannot use this as a way to price 3G devices higher for better profit margins (obvious). 2) the Carriers will raise hell as they dont want all that competition (as users can now switch carriers easily as it becomes a ubiquitous presence in all devices) 3) Carriers will have to run the gamut of 3G tests to insure that their network security isnt "compromised" (the bogeyman argument that carriers always use to thwart any innovation). But I guess some day soon this might be broken just as many other walls have slowly been torn down in the world of carrier-mfrs nexus.
