Why can't the weather on iphone be updated?

IPhone's own weather can't access the weather in small cities. The network status is not good, or the network is not open. It is recommended to try using wifi update. If it still doesn't work, you can restore the network settings in Setup-Restore-Restore Network. This software is only applicable to firmware versions of 2. 1 and above. IPhone weather is an application that highly imitates IOS weather. No desktop plug-ins. Enter the corresponding city name and click Finish to view the weather, and you can add multiple cities.
