> I doubt that there's any way to fake location based on cell towers. That's all done in the baseband radio, which is not readily user accessible. And even if you could mess with it, it's probably very illegal.
Also, it would probably cause your phone to simply stop working as a phone - cell towers need this location data for their fundamental operations as a cellular system.
Yes, good point. So if you care about cell towers, you can just nuke the radio, and use only VoIP via WiFi. But even that's iffy, I think, given difficulty controlling apps. And finally, even if all that works, you don't really have a "phone" anymore.
