iLounge has received an anonymous tip that the Personal Hotspot feature of iOS 4.3 will work on both the iPhone 4 and the iPhone 3GS. According to our source, who tested it using the first beta version of iOS 4.3, the feature works on the 3GS exactly as it works on the iPhone 4, including the ability to share the device’s 3G network connection over Wi-Fi.
Notably, it is up to the individual carriers to support the feature, so while the feature may be present in the OS, it will not show up in users’ Settings app unless it has been enabled by their carrier. In addition, while the feature is present in the current 3GS build of iOS 4.3 beta, it is possible that Apple could remove the feature prior to the public release of the update.
