Apple has released an updated version of its iOS 4.2 GM (gold master) build to developers this afternoon.
GM builds are generally intended to be the final build prior to public release, so this update may well be addressing the WiFi issue many have seen in the first GM build, as earlier rumors indicated. Here’s the brief statement on this at the Apple Developer Member site:
An updated version of iOS 4.2 GM seed for iPad has been posted. If you have already submitted your iOS 4.2 app for review, you do not need to resubmit but retesting is recommended.
The build number for the iPad GM seed has changed from 8C134 to 8C134b.
I’ve just downloaded the new build – so I’ll share some thoughts in the next few days on whether it looks like it has squashed the WiFi issues.
