What are the pros and cons of jailbreaking an iPhone?
My brother wants to jailbreak my iPhone 3G and I am scared of what it might do. Can you undo the jailbreak if you need to take your phone to the apple store? Also is there some website that I can look at that shows what the iPhone can look like?

Pro: Rebellion Against 'The Man':
Apple argues that by keeping firm control over the hardware that runs its software, it's able to maintain quality and a consistent experience. But with all the App Store rejections, limitations on software developers, and usage restrictions (MMS is here finally, but where is tethering?), some people feel constrained by what the iPhone can't do. Apple has been very clear that it isn't happy with iPhone hacking, so if you're the kind of person who likes to rush out of the electronics store without letting the security guard check your receipt, you may find a rebellious thrill in jailbreaking.
Pro: Third-Party Apps Galore:
Cydia and its newer, lighter competitor Icy are the unofficial app stores available only to jailbreakers. In these stores, you'll find hundreds of terrific apps that have been rejected from the App Store for providing features that Apple would rather you not have. Examples? Cycorder is a camera app that enables video-recording on pre-3GS iPhones; PDANet allows tethering of your 3G connection to your laptop; and GVMobile is an app for the Google Voice service. Plus, you can still get free and paid apps from the official App Store, so jailbreakers get the best of both worlds.
Pro: Total UI Customization:
The iPhone's user interface is excellent, but there is just something cool in giving your phone a Snow Leopard facelift. Or making your home screen look like a vending machine. Jailbreaking lets you do that, and much more. With the Winterboard app, you can install any of the vast number of skins available. Jailbreaking also lets you install systemwide add-ons such as SBSettings, which enables quick access to your system settings from within any app. You can even add a fifth icon to the dock at the bottom of all iPhone screens or change system sounds (like adding some new text message tones to the scant built-in set of six). The list goes on and on.
Con: Beware of the Rickroll:
Unless you're a big Rick Astley fan, you're probably not going to want him plastered on your jailbroken iPhone. Jailbroken iPhones in Australia were reportedly infected by a worm that only replaces the device's background wallpaper with an image of 80s one-hit wonder Rick Astley. The worm, dubbed ikee, only affects jailbroken iPhones running the SSH app with the default password. While the worm is fairly harmless and seems to only be limited to jailbroken phones in Australia, malicious variants of ikee could soon follow.
Con: Bye-Bye, Warranty:
Sad, but true: Jailbreaking voids your warranty. If you experience hardware problems with your jailbroken iPhone, don't expect any help from Apple. But you can probably get around that limitation. If you use iTunes to restore a clean version of the iPhone software (not one from a backup), Apple will never know you had previously jailbroken your phone.
Con: Updates Can Break Jailbreaks:
If you're the kind of person who waits in line to buy the latest and greatest Apple hardware, or you worry about the security implications of not installing a new software update, jailbreaking may not be for you. If you install an update on your hacked iPhone, it will likely negate your jailbreak, meaning your phone will still function normally, but all your jailbreak apps and plug-ins will be erased. Although the Dev-Team generally puts out new tools within a week or two after new software is released, you won't be rocking the shiny new features on launch date.
Con: Increased Instability:
Every operating system is prone to crashing every once in a while, and the iPhone OS is no exception. Throw some unofficial, hacker-originated software into the mix and you might experience more crashes. Also, any add-on or UI mod you install could slow down your iPhone.
Con: Security-Breach Risk
Jailbreaking may open up root file-system access, which makes it possible for users to unwittingly do serious damage. For example, if you decide to install openSSH (to allow wireless data transfer between your phone and your computer) and forget to change the default root password, your entire file system could be open to others on the same network, and your personal data could be at risk.
Con: Fear of the Brick:
While the Dev-Team has generally done an adequate job of testing its tools prior to release, cases of users "bricking" their iPhones in the jailbreak process have been known to occur. The jailbreaking tools are as user-friendly and safe as they have ever been, but you should realize that jailbreaking comes with some inherent risks. If you love your iPhone and don't want to gamble the hundreds of dollars it may cost to replace it, jailbreaking may not be your best option.Source(s): Me :)

professionals- some loose cracked apps,none too sturdy some icons and wallpapers,and a few quite ineffective tweaks. Cons-your iphone will run slower drain the battery swifter void your guarantee,whether you production unit fix,apple can tell very rapid that it develop into jailbroke and could not fix until you pay.
