Apple took a lot of heat over their UDID system earlier this year when it was discovered that some developers were misusing the information. And the criticism amplified a few weeks ago when hackers published a list of over a million device IDs.
In response to the hack, Apple released a statement saying that it was going to be replacing the UDID in iOS 6, and was banning the future use of the data. That replacement is called Advertising Identifier, and Apple introduces it in iOS 6 GM…
Apple has seeded iOS 6 GM (Gold Master) to developers this afternoon. The GM version of software is typically the final beta release, used by devs to work out all the kinks before Apple pushes it out to the general public.
And if you happen to be a part of Apple’s iOS developer program, you can find iOS 6 GM in the dev center. Apple has also posted Xcode 4.5 GM. We’re downloading now, and will report back with anything noteworthy.
