Apple pushed firmware 3.1.3 in wild for iPhone 3GS, iPhone 3G, iPhone 2G, iPod touch 1G, iPod touch 2G, and iPod touch 3G. Jailbreaker and unlocker are advised to stay away from the latest firmware release. If you don’t care about jailbreaking then go ahead and hit the update button. At the moment Redsn0w 0.9, Sn0wbreeze and Pwnage tool aren’t compatible/confirmed for firmware 3.1.3 so stay tuned with us for preserving your jailbreak and unlock. You can download iPhone OS 3.1.3 firmware update for offline use here.
This Minor Update Includes
- Fix for iPhone 3GS battery level reporting
- Fix for app crashes on launch
- Fix for app crashes while using Japanese Kana Keyboard
We have some good news from the Dev Team. It is currently possible to jailbreak the iPhone 2G, iPhone 3G, and iPod Touch 1G running OS 3.1.3.
Update 1: [Don’t go near this if you have 3GS, newer ipt2G, or any ipt3G]
Thanks to daring experimenters in the comments, we can confirm that yesterday’s redsn0w works for today’s 3.1.3 update for iPhone 2G. Just point it at the 3.1.2 iPhone 2G IPSW after doing update or restore to 3.1.3. So far we’ve only confirmed this for iPhone 2G. (Note that if this does work for iPhone 3G too, you can *only* use it if you don’t care about the unlock.)
Update 2: [Don’t go near this if you have 3GS, newer ipt2G, or any ipt3G]
Can confirm that this method works for iPhone 3G and iPod touch 1G too. Don’t do it for iPhone 3G if you need an unlock though (really, don’t!). For older iPod touch 2G, we’ll need a small (1-character) change in redsn0w source.
