14 DAY TRIAL // There are a few reasons why owners of an iPhone, iPod touch, or iPad, should resist the temptation to jailbreak their device. This article has an informational purpose describing some situations which pose risks to Apple device owners, should they employ hacks.
Apple's says 'it just works', so it's probably better if you let it Apple develops its hardware and software to work together so seamlessly that any outside intervention that the company doesn't support may reduce the quality of your experience considerably.
Remember those widespread reports of iPod touches rapidly draining their batteries following the installation of iOS 4.0? Well, there's an offset chance most of these reports were posted by jailbroken users. Apple has not enabled multasking for some devices most likely because it is a huge battery drain. Jailbreaking allows owners of an “unsupported” device to activate the feature, but it comes at the cost of crashing apps, sub par performance, and reduced battery life.
You may end up with useless... building material Secondly, and perhaps the most important point, jailbreaking voids your warranty. Should your iPhone get bricked as a consequence of hacking it (this being another reason why jailbreaking is not recommended), Apple will not assist you in troubleshooting whatever problem you may have with it, even under warranty. The company even puts up signs at some of its stores' Genius Bars warning customers not to jailbreak.
Malware
Yes, your read that right. There's the possibility that, should you jailbreak your device, it may get infected with malware. The only two iPhone viruses ever spotted in the wild were reportedly spread across iPhones that had been jailbroken.

Almost every iTunes software update is delivered with under-the-hood code alterations aimed at canceling your jailbreak. Since every iOS software update counts (and even if it doesn't, not many can resist the urge to apply it), your next upgrade may be the last you'll ever see of your jailbreak. To make matters worse, almost every time you'll set out to get your “fix,” you'll most likely need to follow new sets of rules to jailbreak again. A mistake during the jailbreak process may lead to bricking your device.
