In a surprise move, Verizon is allowing the iPhone 4 to be a mobile WiFi device that can share its 3G connection to up to 5 Wi-Fi enabled devices.
This means you can share your iPhone’s 3G internet connection with your iPad or iPod touch when a regular wi-fi connection is not available.
Personal hotspot support comes built directly into the operating system of the Verizon iPhone 4, which is running a new iOS 4.2.5.
According to iPhoneclub.nl, Apple will be bringing the same personal hotspot support to current GSM iPhones with a forthcoming iOS 4.3 update.
The catch is that the functionality is also subject to the approval of individual carriers, requiring them to be onboard for allowing their customers to access the feature. For its part, AT&T has said that it is “evaluating” the hotspot feature and that it has “no plans to announce today”.
