Hackers vs. hackers. FreeHacks vs. AdHacks vs. PaidHacks. Jeremy covered the state of iPhone piracy yesterday, and while the argument over apps rages, the Jailbreak and potential unlock sitch could become just as confusing. Witness the Dev Team's Cat. Bag. Mouse. post which warns against using "unofficial" (according to the Dev Team) versions of, er, the unofficial (according to Apple) iPhone jailbreaking QuickPwn:
THE MOST IMPORTANT THING ABOUT THE UNOFFICIAL QUICKPWN RELEASES IS THAT IF YOU USE THEM, YOU WILL KILL YELLOWSN0W, POSSIBLY FOREVER. That’s because QuickPwn, by its very nature, requires you to already have accepted Apple’s official IPSW, along with its baseband update. If you do that, you will (possibly forever) lose your ability to software-unlock your iPhone 3G.
