iOS 4.3 will support the creation of WiFi hotspots

Boy Genius and GigaOm are both reporting that iOS 4.3 will support the creation of WiFi hotspots and have screenshots in evidence. It seems likely it will be carrier controlled (like tethering) so may not be universal. Kevin Tofel writes that these capabilities in a phone render a MiFi redundant, but I disagree (for now)… I’ve found MiFi devices have far better throughput, recovery from signal drop-outs and battery life compared to a smartphones acting as hotspots. Phone hotspots are useful for emergencies, but for regular use I think it will be a while before phone software can match a dedicated device.
