Even after the updates from Cydia, the weather app does not work in my iphone 4s JB 6.1. I read in several other forums that it worked for few, it may be the ipad or ip5, I cannot get this thing to work on my 4s.
Fixed it I removed the following files using iphoneexplorer on my mac and the problem solved after a restart. /var/mobile/Library/Caches/com.apple.mobile.installation.plist /var/mobile/Library/Caches/com.apple.LaunchServices-045.csstore
