BGR just confirmed that all iPhones great and small will soon be getting the Personal Hotspot feature, although the actual implementation will be carrier specific. Considering Verizon’s move to offer the service, however, I suspect AT&T will follow suit almost immediately.
The feature appears in iOS 4.3, the latest version of the OS to arrive in March. Sadly, this means Verizon will have a brief head start as it releases the device in February. It should also be noted that, as one Tweeter said, Android had this out of the box at launch.
No information on performance or pricing is available, so we’ll all just have to sit on our hands until then.
