The personal hotspot feature for the iPhone was announced during the press conference with Verizon, but the feature will not be limited to Verizon iPhones. All iPhones will reportedly have the feature enabled with the iOS 4.3 update.

We’re sure there will need to be carrier support for this feature, and for AT&T users it is entirely possible we might not see this right away, writes Jonathan Geller. For those of you with more lenient carriers, however, we are sure you will be pleased to learn that you’ll be able to connect up to five devices over Wi-Fi to the iPhone’s cellular data connection. We are told the OS version will be 8F5148b, the baseband will be 04.08.00, and technical acceptance is planned for March.
