if you're on mac, get pwnagetool and find the location of the installer file that the app uses to install it into the custom .ipsw... extract the file and ssh it into your phone. set permissions root:wheel. if you're on windows, get winpwn 2.0.0.4...find the .tar file of installer (c

program files\winpwn\bundles) and extract it and do the same..
im on windows, i found the .tar (in the location above), extracted it...used winscp to ssh it into my phone. set permissions, root:wheel...runs perfectly. have fun. if you need more help...PM.
the easiest way is to upgrade to 2.0.1 honestly...i would have done that but iTunes doesn't like my USB ports so i get an error everytime i try to restore. need a new computer. :-(
