I understand that you are unable to send voice messages using WhatsApp messenger after upgrading to iOS 7. This is likely to be an app issue so I suggest that you update the said app to the latest version. Here`s how: 1. Open the App Store. 2. Press the Update button. 3. Select Update All or scroll to the app and manually update it. In case you are unable to update the app or there`s no new update, deleting the app and re-installing it could help address the issue. To delete the app, tap and hold on its icon on your Home screen until it wiggles. Click the red x button to uninstall it. Now launch the App Store and download it again. If the issue persists, you should contact WhatsApp for an expert opinion. You can reach them at sup...@whatsapp.com.
