Hello, all! I just used the RC5 build of Greenpois0n on a Windows XP to jailbreak my iPod Touch 2nd Gen MC model. I didn't use my Macbook because the OS I'm running (Tiger) doesn't support the RC5 build. The program claims that the jailbreak is done, and the home screen of the iPod shows the "Loader" app (the app icon is white), but when I tap the icon to start the app and load Cydia, the screen flashes white, then returns me to the home screen. I read about something like the problem I'm having, but the listed solutions require me to use Redsn0w to cook the on-board iOS; Redsn0w won't work on MC models... Any help would be MOST appreciated!!!!
