The as-yet unreleased second iteration of iPhone hardware may already be compromised, reports Engadget and News.com. Members of the 'iPhone Dev Team' have (supposedly) made use of the recently released SDK to gin up a Beta 2.0 software hack. "Unlike previous hacks, this one isn't specific to the latest firmware version, it exploits the way that Apple designed the iPhone's main bootloader. According to the iPhone Dev Team, the iPhone verifies whether or not firmware code has been signed with an RSA certificate before allowing it to be written to memory. The team has apparently figured out a way to disable that check and allow unsigned code to be written to memory."
