After releasing an update to iTunes (version 9.0.3) yesterday, Apple today has announced the new iPhone 3.1.3 firmware for iPhone 2G, iPhone 3G, iPhone 3GS and iPod touch. One thing which is to be noted here is that this isn’t the same version which runs on the newly released Apple iPad (OS 3.2). If you currently rely on your unlock for iPhone 3G and 3GS, we highly recommend you not to upgrade to this new iPhone OS 3.1.3 unless and until new tools are made available from the likes of George Hotz and the infamous iPhone DevTeam. Upgrading to iPhone OS 3.1.3 now may result in your device getting potentially locked forever.
Stay tuned as we’ll let you know whenever a workable solution is released for unlocking this latest firmware. In the meantime you can follow our complete unlocking guide for iPhone 3.1.2 firmware using ultrasn0w and blacksn0w.
