Update:
Geohot-Limerain is out for jailbreak your device fw 4.1
Greenpoison by chronic Dev team also out for jailbreak your idevice 4.1
~ this only work for 3gs and iphone 4

Update:
Apple just came out 4.02 os for iPhone on 8.11.10 with the only purpose is to patch the Comex jailbreakme.com exploit. So if you still want your carrier unlock and jailbreak, don't, I repeat DON'T update to the new Apple 4.02 OS.
If you did, and you have a 3GS, i4 you are out of luck. If you have a 3G then you can look back and jailbreak it with redsnow. See redsnow jailbreak tutorial.


Thanks @Comex the creator from Dev Team for http://www.jailbreakme.com, that allow jailbreak on all iDevices, 3G,3GS,iPhone 4 and ipad. And the idevice can be jailbreak directly from the iPhone web browsing plateform, Safari.
So on your idevice open safari and simply enter the web address and slide to jailbreak it. It's that simple and it's free.

Top reasons as to why jailbreak your iPhone?
1. Carrier unlock~ Well, if want to use your iPhone for T-mobile or any other sim carrier, then you have to get it unlock, in order to unlock you need iphone to be jailbroken.
2. Legal now
3. Create and Add unique stuff to your iPhone, themes and sms ringtone and other cool apps that apple felt threatening against their bottomline e.g. GVM (google voice)

For carrier unlock open up Cydia, and go to manage, sources then select repo666.ultrasow.com and it should automatically run and reboot the device.


Enjoy!
