Apple released an iPhone firmware update today, 3.1.3. For those of you jailbroken/unlocked, wait for The Dev Team to update their software before you upgrade your iPhones and iPod Touches. There is word that the current RedSnow will work for the iPhone 2G as long as you point it at the 3.1.2 IPSW.
Stay tuned and I’ll update as soon as the new firmware is jailbroken and unlocked.
