Apple's personal hotspot feature (at least for AT&T iPhone users) has been looming since the release of the Verizon iPhone. This hotspot is only capable of sharing your 3G (or 4G) data connection with 3 wireless devices. It works out well for me in the central time zone, since the update will be over my noon hour.
This is a pretty fast turn around from GoldMaster to a final release of an iOS 4.3 update...it seemed to take forever to get the iOS 4.2.1 for my iPad, that was probably more of a significant update getting iPad, iPhone and iPod on the same version. At least until the Verizon iPhone came about with their Mobile HotSpot feature integration.
It looks like the Dev Team members have a nice start on jailbreaking iOS 4.3, an PwnageTool for iOS 4.3 has already been developed based on the GM and beta versions...and should quickly follow the release.
