So the Galaxy Nexus will work on AT&T 3G and Tmobile 3G with a simple sim swap and changing the APN in settings? Because the Nexus S I have doesn't work like that and yes it is unlocked. Which Blackberry model does RIM sell unlocked that also works on all 3G with a sim swap? Please educate me, and I'll confess that Apple is behind then.
Im curious as well now, so I'll do some research and get back with what I find. Looking at the spec sheet of the Galaxy Nexus, it confirms it would work on both ATT and T-Mobile. However, its to early to tell if carriers or Google themselves would block the user from doing that in their software.
As for whether Apple is behind in technology, it could just be simplicity - I bet less frequency bands equals better quality, smaller chip, lower cost etc.
