Apple has seeded a new Gold Master version of iOS 4.2, labeled iOS 4.2.1, to developers. Unlike the secondary GM seed of iOS 4.2 released exclusively for the iPad, this new build is available for all capable devices, including the iPad, iPhone 4, iPhone 3GS, iPhone 3G, and the second-, third-, and fourth-generation iPod touch. While it is unclear whether Apple now plans to skip a general release of iOS 4.2 and go directly to iOS 4.2.1, an email from Toktumi, makers of the Line2 VoIP application, suggests a communications bug may have led Apple to release the new build. According to the email, reprinted by Mac Rumors, the GM version of iOS 4.2 contained a “severe” bug that caused any VoIP app running in the background to continuously ring after receiving an incoming call, even after the call is answered. The email states that Apple Developer Support is aware of the bug; it is unknown whether iOS 4.2.1 includes a fix for the issue. iOS 4.2.1 GM is available as a download for paid iOS developers from Apple’s iOS Dev Center.
