Jailbreaking may now be legal in the United States but that doesn’t mean Apple is happily supporting it. Apple is still against it (rightly so) and have confirmed that jailbreaking any of their device could void the device’s warranty.
Cult of Mac got the following statement from the Apple PR.
“Apple’s goal has always been to insure that our customers have a great experience with their iPhone and we know that jailbreaking can severely degrade the experience. As we’ve said before, the vast majority of customers do not jailbreak their iPhones as this can violate the warranty and can cause the iPhone to become unstable and not work reliably.”
While Apple wants you to believe that jailbreak is a bad thing to do, there are about 10m jailbroken devices. One reason why Apple is playing the “degrading experience” card could be to refrain users from installing pirated apps, which can be only done after jailbreaking.

More then 70% of Apple devices including MacBook are running with Jailbreak, once the devices are restored Apple has no record if the device were Jailbreak or not.. I give you my own example i got a second hand 3G phone, registered it on iTunes on my name using my account (Now i have no Idea in whose name this device was actually purchase and at which place), i got wifi problem and i went to Genius at San Francisco. Representative of Apple connected the device with their system, checked and printed the details and gave me Mr.Patel this phone is registered at So & So address in Fremont is that correct?? Now all old informations of previous owner was wiped out when i registered in my name. Secondly if you use Pay As You Go from AT&T in your iPhone they will say ok this phone is perfect.. And honestly they personally suggest you to get the device Jailbreak, and if there are any problems they even restore you to factory settings.. (This is my personal experience at Apple & AT&T stores in San Francisco & in New York)..
So i think there should not be any problems even in future with it.
