Apple appears to have finally patched a bootrom vulnerability in the iPhone 3GS which has been used for jailbreaking via the 24Kpwn exploit. Apple replaced the bootrom in units shipped recently with an updated version.
Apple modifying the bootrom eventually was inevitable given the amount of work continue to put into attempting to stop jailbreakers.
This won't affect jailbreaking of older iPhones. But if you were planning to buy a new iPhone with the intention of jailbreaking it you might want to buy a refurbished unit or look for a retailer with older stock.
