The way it's been worded by others, it sounds like it's just a matter of tuning the radio to another frequency. Is the underlying protocol still the same between these providers since it's all just GSM?
- jrockway 17y ago3G is not GSM.
- pyre 17y agoGSM and CDMA are separate from 3G. That's why either of the GSM models of the NexusOne will work on any GSM network and will work with Edge on any network. It's 3G that's different between these networks. Also of note, is that most of these chips target a specific frequency (or frequencies). They are not software programmable radios. I imagine that the underlying protocol possibly differs between the different 3G bands (otherwise I would expect that someone would have created a chip that supports all of the common bands by now).
