Passed iOS 5.1 has completed internal testing or released within several days

According to foreign media reports, reliable sources said that the iOS 5.1 System for iPhone, iPad and iPod has passed Apple's internal quality assurance testing, the official release of this version is expected to be released within a few days. In iOS 5.1, Siri supports Japanese and some new features that are not publicly available.

"Chronic", a hacker from the iOS jailbreak community, said on his blog today that, according to a "very reliable" reporter, iOS 5.1 has recently ended a three-week period of Apple's "strict quality assurance stage", so the final release of this version will be announced within a few days.

The development code of the upcoming iOS 5.1 system is 9B176. In addition to the support for Japanese by Apple voice assistant control application Siri, this version also contains two undisclosed new features.

In addition, the update also simplifies the operation of enabling the camera in the lock screen status. This feature was mentioned in an iOS 5.1 preview screenshot last month.

It is reported that iOS 5.1 has been tested in apple, and major operators and partners are also involved in the test. For this reason, this version has been obtained by many unauthorized people, but because the firmware does not have a digital signature of the external server, unauthorized iOS devices still cannot install the version system.

Apple began to provide developers with the earliest version of iOS last November since 5.1, and then released the second test version on December. The third test version was released in January this year. Since then, Apple has not released any new test versions.

Apple is likely to discuss the iOS 5.1 system at its press conference on Wednesday. The press conference is also widely held to launch the third-generation iPad.
