No!!! They would never know that you're doing it unless you take it in for service. Even then, they'll just deny you warranty work. What you do with your phone is your own business.
Putty is right - for the first time this year, you can legally crack your phone without violating the DMCA. You bought it - it's yours!
It's true that Sprint can't tell from afar if you're phone is rooted or not. But I am wary of people using the "legal" argument to justify rooting. Yes, it's legal. Sprint can't sue you for rooting your phone. But they CAN terminate your warranty and even your service, especially if they find out you are using your root privileges to circumvent their $30/mo tethering charge. Remember, the contract that you sign with Sprint gives them the LEGAL right to cancel your service. So don't think that just because it's legal to root your phone that it trumps any of Sprint's legal rights to cancel your warranty/service. That said, it's nearly impossible for Sprint to find out. You'd have to give your phone to them and have them inspect the OS.
This has been the majority of people's experiences. The techs working for Sprint don't give a shit. It varies from store to store as well. The guys at my store are cool about it. They all rooted their phones (off the record).
I think they expect us to root our devices. I mean why own something and not use it to it's full potential.
The way you phrased it I imagine someone in support at Sprint getting insanely pissed off and throwing a stapler across the office. "Can you believe this a**hole?? HE ROOTED HIS DAMN PHONE! I'M SO PISSED OFF RIGHT NOW"
That made my day after dome d-bag stole a company monitor because the one he has at home broke. P.s. I have about 10 old tube monitors i tried to give him, but you cant give those things away
Yeah that have been my experience to,u really need to come across a real dick head for them to tell you anything.
I was thinking legal dept or someone. Since I read on here that Sprint was sending out cancellation letters, forget which thread.
Legal dept is not in the normal chain of warranty/service issues. If they are, it means you the user threw a huge fuss and threatened to sue. So yeah, if you attract too much attention, you might want to cover all your bases. And that would include unrooting your phone.
