iPhone OS 3.1.3 was launched into the hands of iPhone and iPod touch users everywhere today, but it only a minor update, fixing the accuracy of the iPhone 3GS battery level and where third party applications would not launch. Seems small and worthwhile for some if it weren’t that it would cut your jailbreak. If you don’t experience app crashes on startup, experiencing problems with the the Kana keyboard or don’t have a iPhone 3GS, you need not upgrade and lose your jailbreaking freedom. Until then, it is probably best until the iPhone Dev-Team release an iPhone OS 3.1.3 jailbreak. However, there is a workaround for iPhone 2G users: point the .ipsw during the jailbreak with yellowsn0w to iPhone OS 3.1.2 and restore. iPhone 3G users can use the same workaround if they don’t mind losing unlocking.
