Lots questions. One answer.
"The updated package will be ready when it is ready. And don't worry, you will know, either from here or from blogs or Cydia itself." (Pod2g).
* Those who jailbroke will need to update some packages in Cydia to fix Weather and long boot _when_the_package_is_ready.
* Well, the fix for the Weather app will also be included in the next evasi0n app version.
* Evasi0n will be updated not for the Weather fix (Cydia related) but for long boot issue.
* We're also working on improvements to the long reboot time problem, those should be out with a Cydia update.
