Woke up this morning, approx. 7AM, saw iPhone Dev Team blog posting a sweet greeting of "Good-Morning" where they released their PWNAGE tool version 2.0.2 developed to help you unlock and activate iPhone 2.0.1 firmware.
To download the tool, try here and here.
To grab the iPhone 2.0.1 firmware, its here for 3G and here for 2G/EDGE version.
When I launched PWNAGE 2.0.1, it automatically prompted a new version is available so I was able to download and install with one click. I haven't tested this new version myself, want to be sure if things are stable. Remember, 3G iPhone still can't be unlocked, just jailbroken and rumor has it that you should not do this if you want it to be future update compatible, not certain how true this is.
PWNAGE 2.0.2 is obviously designed to pwn iPhone 2.0.1 firmware which can improve some bugs like slow keyboard and application launch (ie. contacts, etc.), in addition, Cydia (3rd party application installer) has been improved as well as for the first time, Installer 4 (another 3rd party application installer) is build into the firmware. It is the reason why PWNAGE 2.0.2 was delayed from launching on Thursday 8/7/08.
Update: I pwned 2.0.1 using PWNAGE 2.0.2 this morning, its pretty awesome. I documented my instructions here.
