Anyone else having issues with the weather app? So I jail role with the new evasi0n tool and now I can't launch my weather app. Anyone else experiencing similar problems?
This has been noted on a couple of blogs.
The jailbreak screwed up some files. There is a fix which requires you to:

( taken from cult of mac


Open Cydia and install Open SSH and MobileTerminal
Load MobileTerminal and type “su root” (no quotes). Then hit enter.
Enter your password. It’s probably “alpine” if you haven’t changed it yet.
Copy and paste the following script into MobileTerminal

#!/bin/bash
chmod -x /usr/libexec/mobile_installation_proxy
killall -9 mobile_installation_proxy
rm /var/mobile/Library/Caches/com.apple.mobile.installation.plist /var/mobile/Library/Caches/com.apple.LaunchServices-045.csstore
launchctl stop com.apple.mobile.installd
launchctl start com.apple.mobile.installd
while [ ! -f /var/mobile/Library/Caches/com.apple.mobile.installation.plist ];
do
sleep 1
done
while [ ! -f /var/mobile/Library/Caches/com.apple.LaunchServices-045.csstore ];
do
sleep 1
done
sleep 10
chmod +x /usr/libexec/mobile_installation_proxy


sync


reboot
