iPhone and iPod touch coders got their first taste of iOS 4 late on Wednesday when Apple released a beta to Developer Program members. Since developers are bound by a nondisclosure agreement, official information about what the beta includes isn’t publicly available.
Apple has been promising a software update that would address the artificially high signal strength indicator and potential signal degradation issues some iPhone 4 owners have been experiencing, so there is a chance that might be included in this update. The update could also include fixes for the iPhone 4 proximity sensors, and support for Apple’s promised Game Center social service.
Based on early reports, the beta doesn’t include iPad support. Apple released iOS 4 a few days ahead of the iPhone 4 launch, and said iPad support would be added later this year.
There’s no word from Apple on when iOS 4.1 will be available as a public download.
