Jailbreak : Fix For Weather App After Jailbreaking iOS6

So here's my case, Jailbroken iOS6.1 with the initial release of Evasion Jailbreak, already installed Appsync for iOS 6.

What I do is;

1. Remove/uninstall Appsync

2. Reboot

3. Copy the script

#!/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;

4. Open Mobile Terminal

5. Login to root ( command: login root,then your password, default is alpine)

6. Make a new shortcut, and paste the script that you copy and click done

7. Go back to the Main screen of Mobile Terminal and open the Shortcut menu and execute your newly created shortcut

8. Wait till the script is fully loaded (30 sec or 1 minute)

9. Hit enter/return on your keyboard after the "reboot;" is shown, it means the script is done loading

10. Phone will reboot and you should have the Weather App working now

Note : Tested devices iPhone 4s and iPod Touch 4 running iOS 6.1 Jailbroken with Evasion JB
           You can still install Appsync after this fix :p
