It’s was pretty much known that since this is the first version of the JailBreaking tool called ‘evasi0n‘, there would be certain bugs which would be fixed in the next version. Some of them have lately come to the surface which includes crashing of weather application on iPhone or iPod touch once the JailBreak is finished. And in some cases, device took a ridiculous long time to reboot.
Undoubtedly, there’s a workaround for power users to fix the weather application and long reboot issue. But there are users who haven’t yet understood how to deal with them. Hence, team of iOS hackers who are also known as evad3rs have decided that they would push an update of evasi0n soon that would fix these minor issues. If you are one of those people, you should be notified either by Cydia or through the blogs whenever the update is pushed. 
Are you experiencing issues other than them? Let’s know in comment section below.
