According to the manufacturer, maybe. Intrepid Apple blognaut Leander Kahney
rang up Apple
, asked the question above, and got a response
. This was more than we got when several of us asked Apple multiple variations of the same question. Apple's statement, as seen on Cult of Mac:
"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."
Well that's clear as mud, isn't it?
Apple points to a knowledgebase article here
, indicating how much instability you might expect after jailbreaking your iPhone. Of course, now that jailbreaking is legal, Apple can't really go after anyone doing it, but that doesn't mean they have to support your functionality habit, either. Because, as Apple has vaguely worded, it might
void your warranty. Not that it will
-- because if you don't mess with baseband and restore your phone, no one would be the wiser. A simple complete restore really does bring your iPhone, iPod touch, or iPad back to factory conditions.
