(Update 4 !!! PWNAGE 2.0.2 Officially Released! Get it here. I tried it out, working great, my instructions are here.)
(Update 3 !!! iPhone Dev Team just updated an entry titled "It isn't Sparkling - Yet!", a bug is found which may prevent some macs from finalize .ispw build, I covered it here, looks like we got to wait a day or two longer for PWNAGE 2.0.2 to be released)
(Update 2 !!! Finally got through their blog, apparently, they got everything working but yet to release. Any time now. Stay tuned)
(Update 1 !!! Pwnage 2.0.2 Released today - Friday 8/8/08. I can't get through the iPhone Dev Team's blog, must be too many people using them)
The folks building 3rd party app "installer 4.0" will be releasing their app soon, so the Pwnage guys are waiting for that to roll out the build together. Guess we'll have to wait until Friday.
