If yesterday’s announcement of the Verizon iPhone and its promise to be able to generate a Wi-Fi hotspot for up to five mobile devices is the thing that has you contemplating a switch to the carrier, then you might want to wait. Boy Genius Report says that a source tells it that this feature will be coming to all iPhones in iOS 4.3.

Of course, this will likely require carrier support, so AT&T users still might not benefit.

But if this feature is one of those make-or-break reasons why people would switch carriers (well, other than being able to make a phone call, of course), then it’s likely AT&T would follow Verizon’s suit.

According to BGR, the OS version will be 8F5148b, the baseband will be 04.08.00, with technical acceptance planned for March.
