WhatsApp for iPhone requires iOS 7 or later. For the best experience, we recommend you use the latest version of iOS available for your phone. Please visit the Apple Support website to learn how to update your iPhone's software.
Note: iPod and iPad devices aren't supported at this time.
We don't explicitly restrict the use of jailbroken or unlocked devices. However, because these modifications might affect the functionality of your device, we can't provide support for devices using modified versions of the iPhone's operating system.
