Yesterday, the much anticipated iOS 6.1 jailbreak was released. With the wide array of Cydia apps that are newly available to jailbroken iPhones came an unpleasant surprise—evasi0n causes the built-in iOS Weather app to crash over and over.
There will more than likely be a fix on Cydia soon, but if you don't want to wait for it, here's how to fix it yourself. You'll need to have Open SSH and MobileTerminal installed from the Cydia Store.
- Launch MobileTerminal and type "su root" (without the quotation marks), then hit Enter
- Enter your password (if you haven't changed it, it will be "alpine")
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 ;
while ! -f /var/mobile/Library/Caches/com.apple.LaunchServices-045.csstore ;
chmod +x /usr/libexec/mobile_installation_proxy
Alternatively, you can grab the script above here. Once your device reboots, the app should work normally.
