How to jailbreak an iPhone with PwnageTool:
Find out what iPhone you have, iPhone 2G, iPhone 3G or iPhone 3GS or iPhone 4. Then, find
which iPhone software is available from Apple at that time. Then see if a jailbreak
for that iPhone OS is available from the Bigboss website. If yes, then continue. If there is no
jailbreak available for the model or the iPhone OS and if you are already jailbroken, then Don't
update your iPhone to the latest iOS, and wait for a jailbreak to come soon. Check the bigboss site regularly for updates.
If a jailbreak is available for the latest iPhone OS. Then continue.

How to jailbreak an iPhone and still get support from Apple? You can't really get support from Apple if your iPhone is jailbrocken. However, you can always restore it before taking it to Apple for support. Read the iPhone troubleshooting page to learn how to get your iPhone or iPhone 4 to its original state.
Apple of course doesn't want to support those Cydia apps and iPhone hacks, and
want to get involved in any of the issues or iPhone problems jailbreaking
could cause. Therefore, they don't tell you how to jailbreak an iPhone, it is still unofficial, and you lose your warrantee when you jailbreak your iPhone.
Although an iPhone restore with iTunes will simply
it to its official state, and
wouldn't know that it was
jailbrocken previously, Apple will not help you or support you if you
bring a jailbrocken
to their store. So of course never ask any iPhone questions such as "how to jailbreak an iPhone" to an
Why I jailbroke my iPhone:
The main reason for me to jailbreak my iPhone was Arabic
support and Arabic iPhone applications. Apple only added Arabic language support in iPhone OS3.0. Therefore,
by jailbreaking, I was able to install Arabtaller from Cydia that added Arabic. I would have had my iPhone for one year without Arabic language if I
Another reason I got my iPhone jailbrocken is to make cheap
international calls. With Skype and iSIP you can make
cheap international calls if you are connected to wifi only because AT&T restricts you from using
the apps on their 3G or EDGE network. When I jail break my iPhone, I can
use those apps and others to make iPhone VoIP calls using Skype or iSIP. With 3G Unrestrictor,
I can un restrict those applications to run over 3G or EDGE network, and not only on wifi.
Now after I am used to jailbreaking, I can’t manage to use a
non-jailbrocken iPhone ever again.
