The Gold Master(GM) version of iOS 4.1 is available from this moment for all developers of applications intended for the iOS operating system. The GM version is practically the final version of iOS 4.1, only that it is available exclusively to developers and not to regular users. Until now, there have been no differences between the GM versions of iOS and the final versions, and the situation will more than likely be preserved this time, so if you want to test iOS 4.1 from now on and you have the phone registered in a developer's account you can do it
Here's what's new in iOS 4.1:
- solving problems with the proximity sensor of the iPhone 4;
- solving problems with bluetooth;
- solving performance problems for iPhone 3G.
This version of iOS 4.1 comes with a new baseband and blocks the jailbreak done through jailbreakme.com, but theoretically redsn0w can jailbreak this version. If you have an iPhone 3G registered to a developer's account and you want to test this version of iOS, you can download it, test it and possibly jailbreak it with the latest version of redsn0w.
UPDATED : It seems that the version has been available for some time for developers.
