Jailbreakme Now Jailbreaks All iOS Devices
Wow! Jailbreaking has never been easier.
You can now jailbreak your iPhone, iPod Touch, or iPad right from MobileSafari — no PC or Mac needed!
Just visit http://jailbreakme.com on your device.
For those needing a carrier unlock, use the existing ultrasn0w in Cydia on your iPhone3G or iPhone3GS.
Apparently, there was so much traffic the sever went down, it should be back up now.
Note: There are currently some issues involving MMS and Facetime being disabled, and those are being worked on.
