Well I'm not on sprint but I'm sure every phone carrier allows this...

As for those who think this is an invasion of privacy...
The second you step out of your house you have given that right up! Phone or no phone! All this does is make following someone easier!

I would rather they trace GPS data instead of raising my taxes to hire and physically assign an agent to follow everyone they want to track!

And I'm happy to let them know where I am every second of every day if it means 3000 people won't get killed in some terrorist attack!

None of that data would be admissible in court anyway because all it would prove is your phone went somewhere, not you yourself.
And even if you went someplace people should not be going they still can't prove you did anything wrong!!! That is until Sprint gives them the ability to turn on your camera and listen into your conversations!

So I think it's much ado about nothin!
